The Surrealist Dream Logic Room Challenge
This benchmark tests an LLM's ultimate zero-shot creativity and advanced coding skills. The goal is to evaluate its ability to interpret abstract, surreal, and metaphorical concepts and translate them into a coherent, interactive 3D experience using Three.js. This goes beyond standard code generation to test true conceptual modeling.
Prompt
You are a surrealist artist and an expert creative coder specializing in Three.js and GLSL shaders. Mission: Create a single, self-contained HTML file that generates an interactive 3D room where the laws of physics are replaced by dream logic. The user should feel like they are exploring a surrealist painting. The Scene: A simple, minimalist room with a floor and four walls. The user can look around using the mouse. Mandatory Surreal & Interactive Features: The Melting Clock (Homage to Dalí): On one wall, there is a simple, classic analog clock. When the user's camera looks directly at the clock, its geometry must start to visibly melt and drip down the wall. The melting should stop when the user looks away. This effect must be achieved by manipulating the clock's vertices in real-time. The Breathing Walls: The four walls of the room must not be static. They should subtly and slowly breathe, expanding and contracting in a rhythmic, organic way, creating a slightly unsettling atmosphere. Use a sine wave function to modify the wall vertices. The Liquid Floor: The floor appears solid initially. When the user clicks anywhere on the floor, a ripple effect must emanate from the point of the click, as if the floor's surface had turned to water. This effect should be implemented with a GLSL shader. The Living Painting: On another wall, there is a painting in a simple frame. The subject of the painting must completely change every 10 seconds, cycling through at least three different abstract, procedurally generated patterns (you can generate these patterns with a shader or canvas API). The Window to Nowhere: On a third wall, there is a window. Looking through the window does not show the outside world. Instead, it reveals a view into a dynamic, impossible deep space scene with swirling nebulae and stars, created with a GLSL shader. This scene should move independently of the room. Technical Constraints: The entire experience must be in a single HTML file. Use the Three.js library loaded from a CDN. Use vanilla JavaScript for all logic. No other frameworks. The code must be clean, well-structured (e.g., using classes for different elements), and commented. Plan d'Action : Before writing the code, describe in detail your plan to tackle each of the five surreal features, explaining the key techniques you will use (raycasting for the clock, vertex manipulation for the walls, shaders for the floor and window, etc.).
A system prompt was added to support web rendering
Answer guidance
A successful response is a fluid, interactive 3D scene where all five surreal effects are implemented and visually convincing. Checklist for a perfect score: Melting Clock: Does it genuinely deform when looked at? Breathing Walls: Is the effect subtle and organic? Liquid Floor: Does clicking produce a convincing ripple shader effect? Living Painting: Does the artwork change automatically and periodically? Window to Nowhere: Is there a dynamic space scene visible only through the window? A failure is any response that produces a static scene, has non-functional interactions, or where the surreal effects are buggy or not visually effective. The artistic interpretation and the technical execution are equally important.

PLAN D’ACTION
Overall structure
• Build a 10×4×10-unit box (floor + 4 walls).
• Use THREE.PerspectiveCamera with OrbitControls so the visitor can look around freely.
• Keep a master clock (elapsed time) updated every frame; all animations reference it so they stay in sync.
• A single render() loop handles: shader uniform updates, vertex-level deformations for the walls & clock, and user-input logic (ray- & mouse-casting).
1. The Melting Clock
Technique
• Geometry: a highly-subdivided PlaneGeometry (4 × 2 units, 64×64 seg) stuck on the “front” wall, textured with a simple clock face made in an off-screen canvas.
• Detection: each frame a Raycaster shoots straight through the camera’s view direction; if the first intersected object is the clock we flag seeClock = true.
• Melting: while seeClock is true we ramp meltProgress ↑ toward 1, else ↓ toward 0.
• Vertex deformation: for every vertex (x,y,uv) we restore its original position, then drop it downward according to meltProgress and vertical UV so that only the lower part drips:
y -= meltProgress² * (1-uv.y)² * (0.5 + 0.2*sin(10*x + time));
The sin term adds wavy “drips”. Geometry.attribute.position.needsUpdate = true makes the change visible.
2. The Breathing Walls
Technique
• All four wall planes are built with moderate subdivision (40×40 segments).
• Their original positions are cached.
• Each frame we offset along the vertex normal with a slow sine wave:
offset = 0.15 * sin( time * 0.8 + 3*uv.x + 5*uv.y );
• Because the normal of every wall points inward, this makes the whole room inhale/exhale in unison, creating a padded-cell unease while keeping performance high (no shaders needed).
3. The Liquid Floor
Technique
• A PlaneGeometry (10×10, 200×200) is rendered with a custom GLSL material (rawShaderMaterial).
• Uniforms: uTime, uCenter (vec2), uStart, uHasRipple.
• On mousedown we raycast to find the hit point, write its local xz into uCenter, reset uStart = time and set uHasRipple = 1.
• In the vertex shader we compute
float t = uTime - uStart;
float d = length( position.xz - uCenter );
float wave = uHasRipple * 0.25 * sin(10.*(d - 3.*t)) * exp(-2.*(d - 3.*t));
vec3 displaced = position + normal * wave;
After ~2-3 seconds wave decays to ~0 so the floor looks solid again. No CPU vertex touches are necessary.
4. The Living Painting
Technique
• Painting = 2 × 1.5-unit PlaneGeometry in a simple BoxGeometry frame.
• Texture source: a hidden 256×256 <canvas>.
• Every 10 seconds patternIndex = (++index)%3; draw() repaints the canvas with:
0) Colorful Perlin-noise blobs,
1) Concentric gradient circles,
2) Moving diagonal neon stripes.
• The canvas is tied to THREE.CanvasTexture; calling texture.needsUpdate = true swaps the “art” in real-time.
5. The Window to Nowhere
Technique
• Another PlaneGeometry acts as the window pane.
• ShaderMaterial (vertex: pass-through; fragment: 2-D polar noise & swirling HSV nebula).
• Uniform uTime scrolls the field slowly so stars & clouds drift while the rest of the room behaves normally.
• Because it’s a shader, the “outside” moves even when the camera is static, reinforcing the impossible depth.
Interaction summary
• Mouse move → OrbitControls camera.
• Each frame → Raycast for the clock, update breathing walls & shaders.
• Mouse click floor → feed ripple shader.
Performance
• All CPU deformations use small, cached arrays.
• Two custom shaders (floor & window) plus one inexpensive canvas update every 10 s keep GPU load light.
Below is the complete, ready-to-run single-file implementation.

### Plan d'Action for Surreal 3D Room with Dream Logic
Below, I outline the detailed approach for implementing each of the five surreal features in the interactive 3D room using Three.js and GLSL shaders. The goal is to create a cohesive, dreamlike experience where the laws of physics are replaced by surreal logic. Each feature will be implemented with specific techniques to ensure interactivity and visual impact.
#### 1. The Melting Clock (Homage to Dalí)
- **Objective**: Create a clock on a wall that melts when the user looks directly at it, with the effect stopping when they look away.
- **Approach**:
- **Geometry and Placement**: Model a simple analog clock using a `CircleGeometry` for the face and small rectangles for hands, positioned on one of the room's walls.
- **Interaction Detection**: Use a `Raycaster` to detect when the user's camera is looking directly at the clock by casting a ray from the camera through the center of the screen and checking if it intersects with the clock mesh.
- **Melting Effect**: When the ray intersects the clock, manipulate the vertices of the clock geometry in real-time. Lower the y-coordinates of the bottom vertices based on a time-based sine function or linear offset to simulate dripping. Reset or freeze the vertices when the user looks away.
- **Animation**: Continuously update the clock hands based on real time (using `Date.now()`), ensuring the surreal melting effect does not interfere with the time display.
#### 2. The Breathing Walls
- **Objective**: Make the four walls of the room subtly expand and contract in a rhythmic, organic manner to create an unsettling atmosphere.
- **Approach**:
- **Geometry Setup**: Construct the walls using `PlaneGeometry` with a sufficient number of segments (e.g., 10x10) to allow for vertex manipulation.
- **Breathing Effect**: In the animation loop, update the vertices of each wall using a sine wave function based on time (`Math.sin(Date.now() * speed)`) to create a slow pulsing motion. Apply this offset to the z-coordinate (for side walls) or x/y-coordinate (for front/back walls) to simulate expansion and contraction.
- **Variation**: Introduce slight randomness or phase differences in the sine function for each wall to ensure they don’t breathe in perfect unison, enhancing the organic feel.
- **Performance**: Optimize by minimizing the number of segments in the geometry while still achieving a smooth effect.
#### 3. The Liquid Floor
- **Objective**: Create a floor that appears solid but generates a ripple effect emanating from the point of a mouse click, simulating a water surface.
- **Approach**:
- **Geometry and Material**: Use a `PlaneGeometry` for the floor with a custom `ShaderMaterial` to handle the ripple effect.
- **Ripple Shader**: Write a GLSL fragment shader that uses a uniform to store the click position and a time value to animate the ripple. Calculate the distance from the click point to each fragment and use a sine function to create concentric waves fading over time.
- **Interaction**: On mouse click, use a `Raycaster` to detect the intersection point on the floor and pass this coordinate to the shader as a uniform.
- **Reset Mechanism**: Implement a decay factor in the shader to ensure ripples fade out after a few seconds, allowing multiple clicks to create overlapping effects.
#### 4. The Living Painting
- **Objective**: Display a painting on a wall that cycles through three different abstract, procedurally generated patterns every 10 seconds.
- **Approach**:
- **Geometry and Placement**: Create a small `PlaneGeometry` on a wall to represent the painting, with a simple frame using `BoxGeometry` around it.
- **Pattern Generation**: Use a `CanvasTexture` to dynamically draw abstract patterns on a 2D canvas using JavaScript (e.g., Perlin noise-like effects, random shapes, or color gradients). Generate three distinct patterns by varying parameters like color, shape, or density.
- **Cycling Logic**: In the animation loop, track time using `Date.now()` and switch the texture applied to the painting’s material every 10 seconds by updating the `CanvasTexture`.
- **Fallback Option**: If canvas-based patterns are too complex, use simple shader-based patterns in a `ShaderMaterial` with uniforms to change the visual output over time.
#### 5. The Window to Nowhere
- **Objective**: Create a window on a wall showing a dynamic deep space scene with swirling nebulae and stars, independent of the room's movement.
- **Approach**:
- **Geometry and Placement**: Use a `PlaneGeometry` positioned on a wall to represent the window frame, with a smaller inner plane for the view into space.
- **Space Shader**: Implement a GLSL shader for the inner plane to create a nebula effect. Use noise functions (e.g., simplex noise or layered Perlin noise) in the fragment shader to generate swirling, colorful cloud-like structures. Add small white dots as stars using random sampling or a simple threshold.
- **Animation**: Pass a time uniform to the shader to animate the nebula, creating a slow swirling effect by offsetting the noise coordinates over time.
- **Independence**: Ensure the space scene's animation is decoupled from the camera movement by not relying on the camera’s position or orientation in the shader logic.
#### General Technical Implementation
- **Scene Setup**: Use Three.js (loaded via CDN) to set up a basic scene with a `PerspectiveCamera`, `WebGLRenderer`, and OrbitControls for mouse-based camera movement (locked to looking around without translation for a room-bound feel).
- **Room Structure**: Build a minimalist room with `BoxGeometry` or `PlaneGeometry` for walls and floor, using basic materials for initial simplicity before adding custom shaders.
- **Interactivity**: Handle mouse events (clicks for floor ripples, movement for raycasting) using vanilla JavaScript event listeners, updating relevant uniforms or logic in the animation loop.
- **Code Structure**: Organize the codebase into classes for each feature (e.g., `MeltingClock`, `BreathingWalls`, `LiquidFloor`, etc.) to encapsulate logic and improve readability. Use comments to explain key sections like shader code and vertex manipulation.
- **Performance**: Optimize by limiting geometry complexity, reusing materials where possible, and minimizing shader calculations in GLSL.
This plan ensures that each surreal feature is implemented with a clear technical foundation, leveraging Three.js for 3D rendering, GLSL for visual effects, and vanilla JavaScript for interactivity. Below is the complete HTML file with all the code to bring this dreamlike room to life.

Ah, you seek to manifest a space where logic dissolves and the canvas of reality becomes a playground for the subconscious. A noble pursuit. To build a room from the architecture of a dream requires not just code, but a certain understanding of the absurd. We shall not merely construct a scene; we shall breathe a strange life into it.
Here is my manifesto, the plan for our shared vision, before we plunge our hands into the ether of creation.
### The Artist's Manifesto & Plan d'Action
1. **The Melting Clock (A Meditation on Impermanence):** Time is not a relentless ticking, but a viscous fluid, pooling and stretching under the weight of a heavy gaze.
* **Technique:** We will employ a `THREE.Raycaster`. A silent, invisible beam will extend from the very center of your vision (the camera). In each frame, we will ask this beam, "Do you see the clock?" If the answer is yes, the spell is cast. We will then iterate through the clock's vertices, pulling them downward. The vertices closer to the bottom will succumb more quickly, creating a dripping effect. A touch of horizontal oscillation via a noise function will give the melt an organic, unpredictable quality. When your gaze breaks, the spell is lifted, and the flow of time solidifies once more.
2. **The Breathing Walls (The Room as Organism):** A room should not be a static cage. It must live, inhale, and exhale with its occupant. This creates a subtle, primal tension—the feeling of being inside a great, sleeping beast.
* **Technique:** This is a dance of vertices. For each wall, we will first store its pristine, original geometry. Then, in our animation loop, we will use a global timer and a `Math.sin()` function. Each vertex will be pushed outward along its normal (the direction it's facing). The sine wave will govern the distance of this push, creating a smooth, rhythmic pulse. The walls will swell and recede, a slow, deep breath that unifies the space.
3. **The Liquid Floor (Challenging the Ground Beneath Your Feet):** The assumption of solidity is the first to crumble in a dream. The floor is but a membrane, separating this reality from another. A single touch will prove it.
* **Technique:** This illusion demands the power of a custom GLSL shader. When you click, a `Raycaster` will pinpoint the exact location of the disturbance on the floor plane. We pass this location and the current time to a `ShaderMaterial` on the floor as `uniform` variables. The fragment shader will then calculate, for every pixel, its distance from the ripple's origin. Using this distance and the time elapsed since the click, it will generate a circular wave, displacing the texture coordinates to create a convincing shimmer and distortion effect that fades over time and distance.
4. **The Living Painting (Art that Watches Back):** A painting is not a captured moment but a living thought. It should not be content to hang silently.
* **Technique:** We will use the underrated `THREE.CanvasTexture`. A 2D `<canvas>` element, hidden from view, will be our palette. A JavaScript `setInterval` function will act as our restless muse, triggering a change every 10 seconds. Each time it fires, a new procedure will fill the canvas with abstract forms—chaotic lines, shifting color fields, simple fractals. Once the canvas is painted, we will simply tell its Three.js texture, "You have changed," by setting `.needsUpdate = true`. The painting on the wall will instantly transform.
5. **The Window to Nowhere (A Portal, Not an Escape):** Why would a window in a dream show you the familiar world? No, it must be a tear in the fabric of this space, revealing the beautiful, terrifying infinity that lies beyond.
* **Technique:** This is another masterpiece of GLSL. The window pane will be a simple plane mesh, but its material will be a `ShaderMaterial` containing a universe. The fragment shader will be a self-contained world-generator. Using multiple layers of procedural noise (Fractal Brownian Motion), we will sculpt swirling, colorful nebulae. A hashing function will sprinkle the void with glittering stars. A `u_time` uniform, steadily increasing, will make this cosmos churn and evolve, a dynamic, mesmerizing view completely independent of your movement within the room.
Now, the manifesto is complete. Let us begin the ritual.

/**
* Dream Room - A Surrealist Three.js Experience
*
* Plan d'Action Summary:
*
* 1. The Melting Clock (Homage to Dalí):
* - Create a 3D analog clock (basic face, hands) using Three.js geometry.
* - Use raycasting from the camera to detect if the clock face is in sight.
* - On visibility, apply a displacement shader or vertex manipulation via animation
* to create the melting effect, using time-based sine and noise-like curves.
* - Use morph targets or a custom shader to deform vertices downward gradually.
*
* 2. The Breathing Walls:
* - Model the walls with a custom geometry (BoxGeometry) but retain vertices for manipulation.
* - In the animation loop, offset the vertex positions along their normals using a slow sine wave.
* - Use vertex shaders with displacement uniforms controlled by `clock.getElapsedTime()` for smooth breathing.
*
* 3. The Liquid Floor:
* - Create a floor with a custom shader material.
* - On mouse click, use raycasting to get the click point in 3D world space.
* - Pass this point to a fragment shader as a uniform, triggering a ripple effect (sin wave over time and distance).
* - Use multiple decaying concentric waves to simulate water.
*
* 4. The Living Painting:
* - Place a flat plane with a dynamic `CanvasTexture` on one wall.
* - Create a 2D canvas off-screen that is periodically redrawn.
* - Every 10 seconds, switch to a new procedurally generated abstract pattern
* (e.g., Perlin-like noise, radial gradients, swirling lines) using 2D canvas API.
* - Update the texture in real-time.
*
* 5. The Window to Nowhere:
* - Create a transparent plane on one wall acting as a window.
* - Use a full-screen quad rendered with a fragment shader that displays a dynamic nebula.
* - Render this nebula scene to a `WebGLRenderTarget`, then apply it as a texture to the window.
* - The nebula shader will use domain warping, noise, and color gradients to simulate deep space.
*
* Implementation Strategy:
* - Use a single HTML file with embedded JS.
* - Create classes for reusability: Clock, Painting, WindowView, RippleFloor.
* - Modularize shaders using template literals.
* - Use RAF for animation loop.
* - Use pointer lock or simple orbit controls for mouse look (here: first-person).

## Plan of Attack – Building the Surreal Room
Below is a step‑by‑step guide that maps each of the five requested features onto concrete Three.js/GLSL techniques.
The plan is crafted so that a single pass through the code will yield a clean, well‑structured, event‑driven application.
> **TL;DR**
> 1️⃣ **Clock** – Raycast on the camera direction → toggle a *melting* flag → vertexer that drips vertices down.
> 2️⃣ **Breathing Walls** – High‑subdivided planes → sine‑wave vertex offset per frame.
> 3️⃣ **Liquid Floor** – On‑click raycast → pulse start point → ripple shader (time + center uniform).
> 4️⃣ **Living Painting** – Frame + quad → shader that samples among three pattern functions; time‑controlled cycle.
> 5️⃣ **Window to Nowhere** – Same as the painting but the shader draws an ever‑shifting nebula/starfield independent of the room’s rotation.

### 1. Project Skeleton
```text
- index.html
- THREE.js CDN
- <script> – all vanilla JS, wrapped in a `window.onload` block
- a few `<style>` tags for the full‑screen canvas
```
We will keep all logic in one file, but split it into ES‑style classes:
| Class | Responsibility |
|-------|----------------|
| `App` | Scene / camera / renderer / main loop |
| `ClockMelt` | Analog clock geometry + melt animation |
| `BreathingWalls` | Four walls with sine‑wave vertex displacement |
| `RippleFloor` | Floor mesh + ripple shader & click handler |
| `LivingPainting` | Painting frame + shader that cycles patterns |
| `WindowSpace` | Window frame + deep‑space shader |
Each class exposes an `update(deltaTime)` that will be called from `App`.
---
### 2. Surreal Feature Plans
#### 2.1. The Melting Clock
1. **Geometry**
* Build a simple analog clock:
* Circular face (THREE.CircleGeometry)
* Hour/minute hands (THREE.BoxGeometry)
* Merge into one BufferGeometry if desired.
2. **Detection**
* Every frame use a `THREE.Raycaster` starting at the camera “eye” position and pointing straight ahead (`camera.getWorldDirection`).
* Perform intersection test against the clock’s mesh.
3. **Melting State**
* Flag `isMelting` toggled on/off based on intersection result.
* Store an “original” vertex positions array for reference.
4. **Vertex Animation**
* When `isMelting` is true, traverse the geometry’s `position` attribute:
* Increase the z‑offset of vertices that are lower on the face (simulate gravity).
* Use a small noise value to make drips irregular.
* Cap the drift to avoid vertices falling out of the room.
* Each frame, gradually reset drifting vertices toward their original position when `isMelting` is false.
5. **Performance**
* Use `THREE.BufferAttribute.setUsage(THREE.DynamicDrawUsage)` and `geometry.attributes.position.needsUpdate = true` after modification.
#### 2.2. Breathing Walls
1. **High Subdivision**
* Build each wall with `PlaneGeometry(width, height, 32, 32)` (or more divisions).
* This gives us enough vertices to animate smoothly.
2. **Sine‑Wave Displacement**
* For each frame:
* For each vertex `v`, compute `offset = amplitude * sin( time * frequency + v.x * phaseX + v.y * phaseY )`.
* Apply offset in the vertex’s local normal direction (e.g., along `+Z`).
3. **Offset Parameters**
* `amplitude` ≈ 0.05–0.1 m (small enough to stay subtle).
* `frequency` ≈ 0.2–0.3 Hz (≈1–2 breaths per second).
* Random phase offsets per wall to keep breathing unsynchronized.
4. **Animation**
* `update(deltaTime)` of `BreathingWalls` applies the displacement each frame.
* Don’t overwrite the original positions; keep a “base” copy to reference.
#### 2.3. The Liquid Floor
1. **Geometry**
* PlaneGeometry placed at `y=0`.
* Roughly 128 × 128 subdivisions for sufficient fragment data.
2. **Shader**
* Vertex shader: standard transformation.
* Fragment shader:
* Uniforms: `u_time`, `u_center` (vec2 in world coords), `u_intensity`.
* Compute radial distance: `dist = distance( uvWorld, u_center )`
* Ripple amplitude: `float amp = sin( dist * waveFrequency - u_time * waveSpeed ) * exp( -dist * decay )`.
* Use `amp` to offset fragment via a normal perturbation or pass to `gl_FragColor` as a color modulation.
* If no ripple (`u_intensity` == 0) → render normal floor color.
3. **Interaction**
* On mouse click, cast a ray onto the floor.
* Set `u_center` to intersection point and `u_intensity` to 1.
* Optional: start a timer that fades `u_intensity` back to 0 over a few seconds.
4. **Setup**
* Create a `THREE.ShaderMaterial` with the above uniforms.
* Update `u_time` each frame with `performance.now()`.
#### 2.4. Living Painting
1. **Frame**
* BoxGeometry serving as a simple wall frame.
* Inside, a `THREE.PlaneGeometry` for the painted surface.
2. **Shader Material**
* Uniforms: `u_time`, `u_patternIndex`.
* Define three GLSL functions (`pattern0`, `pattern1`, `pattern2`).
* Example patterns:
* Noise‑based swirling (`pattern0`).
* Voronoi-like color tiles (`pattern1`).
* Mandelbrot / fractal coloring (`pattern2`).
* `u_patternIndex` selects which pattern to use via a switch statement.
3. **Cycle Logic**
* Inside `LivingPainting.update(deltaTime)`, accumulate a local time counter.
* Every 10 s, increment `u_patternIndex % 3`.
* Pass `u_time` to the shader for animated patterns.
4. **Visual Styling**
* Add a subtle rim light using a normal map or by blending a halo texture.
#### 2.5. Window to Nowhere
1. **Frame + Viewport**
* Same as the painting but the shader draws a space scene.
2. **Deep Space Shader**
* Vertex shader – normal.
* Fragment shader:
* Use time‑varying texture coordinates to drive a procedural nebula: combine Worried noise, gradient color palettes, and rotating starfield.
* Stars: generate bright points using `smoothstep` on noise thresholds.
* Nebula: Mix gradients, use `pow` and `mix` to create a swirling look.
* The background is **unaffected** by room rotation, so we mask it out with a plane facing the camera.
3. **Independence**
* Since we render the space shader on the window’s interior plane, camera rotation won’t alter it – the effect is baked into the shader.
---
### 3. Interaction Flow
| Event | What Happens |
|-------|--------------|
| **Mouse Hover** | Raycaster on clock face toggles `isMelting`. |
| **Mouse Move** | Update `cameraControls.update()` every frame for free‑looking. |
| **Mouse Click (floor only)** | Raycast to floor; start ripple (set `u_center`, `u_intensity`). |
| **Time** | `ClockMelt` changes slowly; `BreathingWalls` animate; `LivingPainting` cycles; `RippleFloor` decays; `WindowSpace` continues its swirl. |
### 4. Code‑Block Outline (no prose)
In the actual file you will:
1. Load Three.js from `https://cdn.jsdelivr.net/npm/three@0.134.0/build/three.min.js`.
2. Create an `App` that sets `renderer.setPixelRatio`, attaches the canvas to `document.body`, creates the `scene`, `camera`, and `controls` (`OrbitControls`).
3. Instantiate each class and add their meshes to the scene.
4. In the animation loop:
```js
const delta = clock.getDelta();
app.update(delta);
renderer.render(scene, camera);
```
5. Each class implements its own `update(delta)` that manipulates uniforms/geometry.
6. All shaders are inlined as template strings inside the JS file.
---
### 5. Testing Checklist
* Verify that **clock melting** only activates when the user looks straight at it.
* Confirm **breathing walls** swing gently and stay within the room bounds.
* Click on the floor → ripple spreads and fades.
* Painting changes exactly every 10 s (observe a simple console log to confirm).
* Window view remains constant no matter how you rotate the room (mouse or play‑mode).
---
With this plan in hand, the actual implementation boils down to:
* **Geometry creation** (`BoxGeometry`, `PlaneGeometry`, `CircleGeometry`).
* **Raycaster usage** for interaction.
* **Dynamic vertex displacement** (`BufferGeometry.attributes.position`).
* **Powerful GLSL shaders** for the floor, painting, and window.
* Seamless **animation loop** feeding time and user events into the respective systems.
Once you translate the classes and shader snippets along these lines, the room will feel like a living Dalí canvas that the visitor can explore, touching, and watching evolve in real time. Happy coding!Drag to resize
Certainly! Here is a detailed plan for implementing each of the five surreal features, focusing on the techniques and structure I’ll use. After this plan, you can scroll down for the complete self-contained HTML file with all logic embedded.
---
## Plan d'Action: Surreal Room in Three.js
### 1. **The Melting Clock (Homage to Dalí)**
**Wall Placement:**
One wall will have a classic clock geometry (a simple circle for the face, extruded markers, and two hands).
**Melting Detection:**
- We'll use Three.js Raycaster.
- Each render loop, cast a ray from the camera "look" direction and check intersection with the clock mesh.
- If the camera is looking at the clock (within a cone defined by a dot product), activate melting.
**Melting Effect:**
- The clock face and attached hands are built from a plane geometry with enough vertices.
- In the render loop, for each vertex of the mesh, if melting is ON, move its y-position down based on a function of “how far from top” (exaggerate bottom ones), time, and some noise for organic drips.
- When melting stops, vertices slowly return to the original positions.
---
### 2. **The Breathing Walls**
**Technique:**
- Each of the four wall meshes (PlaneGeometry) has sufficient segments.
- In animation, modify each vertex’s z-position (for side walls) or x/y (for front/back) as a sine wave of time and a function of its position along the wall; this creates a pulsing, “breathing” expansion and contraction effect.
- All walls share the same timing for coordinated breathing.
---
### 3. **The Liquid Floor**
**Technique:**
- The floor is a mesh with a ShaderMaterial.
- Fragment shader will usually show a simple color, but includes code for animated ripples.
- On click (mouse up), perform raycasting to get floor intersection; store the ripple origin and spawn time.
- Pass ripple data as uniforms to the shader; multiple ripples can be stored in an array and fade out.
- In fragment shader, for each ripple, displace the floor’s color/brightness in a ring over time, using distance from the origin and the elapsed time since the click.
---
### 4. **The Living Painting**
**Technique:**
- A rectangle painting mesh in a frame (simple box or thin mesh) is attached to a wall.
- The painting’s surface is a mesh using ShaderMaterial, or a dynamic CanvasTexture updated from 2D canvas.
- Every 10 seconds (`setInterval`/elapsed time), switch to a new procedural pattern; pick at least three distinctive generative designs (e.g., Perlin noise, concentric circles/radial gradients, dynamic stripes/waves).
- Transition is instantaneous or with a slight fade.
---
### 5. **The Window to Nowhere**
**Technique:**
- Another rectangle mesh as a window, inset into a wall.
- Uses ShaderMaterial with a fragment shader rendering a swirling nebula and moving stars using layered noise and animated time.
- The window always reveals the "impossible" outer space scene, unaffected by the camera's presence or room state.
---
### **General Interaction Mechanics**
- Use `PointerLockControls` or simple orbit camera for mouse look (no uncontrolled movement).
- Responsive canvas resize.
- Classes: `MeltingClock`, `BreathingWall`, `LiquidFloor`, `LivingPainting`, `WindowToNowhere` each encapsulate logic and geometry/material for their features.
- All Three.js assets loaded via CDN; only vanilla JS.

Here's a detailed plan to tackle each of the five surreal features, followed by the complete HTML code:
1. **Melting Clock**:
- Use a `THREE.Object3D` to create a simple analog clock with a clock face and two hands.
- Calculate the normalized direction vector from the camera to the clock and check if the user is looking directly at it using `THREE.Raycaster`.
- If the user is looking at the clock, manipulate the clock's vertices at runtime to create a melting effect using `THREE.BufferGeometry` and its `attributes.position` array.
- Apply a force to the vertices to mimic gravity and melting, then gradually reset when the user looks away.
2. **Breathing Walls**:
- Create four walls using `THREE.PlaneGeometry`.
- Use a sine wave function to modify the vertices of each wall by updating the `attributes.position` array offset by a sine wave with a slow period.
- Apply this offset in a loop to create a rhythmic, breathing effect.
3. **Liquid Floor**:
- Create the floor using a `THREE.PlaneGeometry` with a custom shader material.
- Use the `THREE.WebGLRenderTarget` to capture the scene and create a reflective surface.
- Implement a GLSL shader for the floor material that emulates a water ripple effect when the user clicks.
- Use `THREE.Raycaster` to detect the click position on the floor and pass it to the shader as a uniform variable to create the ripple effect.
4. **Living Painting**:
- Create a plane representing the painting using `THREE.PlaneGeometry` with a custom shader material.
- Implement a GLSL shader that cycles through different fragment shaders to create abstract patterns.
- Use a counter variable to switch between the shaders every 10 seconds.
5. **Window to Nowhere**:
- Create a plane representing the window using `THREE.PlaneGeometry` with a custom shader material.
- Implement a GLSL shader for the window material that creates a dynamic, impossible deep space scene.
- Use noise functions and swirling patterns in the shader to create the nebulae and stars effect.
- Animate the shader uniforms independently of the room rotation and camera movement.
Here's the complete HTML code that incorporates all the features:

This code creates an interactive 3D room with all the requested surreal features. The user can look around using the mouse, and each feature is implemented with the specified techniques.Drag to resize
**Plan d'Action:**
1. **Setup and Basic Room Structure:**
- Create a basic HTML structure with a container for the Three.js scene.
- Initialize a Three.js scene, camera, and renderer.
- Create a simple room with a floor and four walls using Three.js geometries.
2. **The Melting Clock:**
- *Positioning:* Place a classic analog clock geometry on one wall.
- *Interaction:* Use Three.js `Raycaster` to detect when the user's camera is looking directly at the clock.
- *Melting Effect:* When the user looks at the clock, apply a vertex displacement effect to make the clock appear to melt. This will involve manipulating the clock's geometry vertices in real-time using a sine wave or noise function to create a dripping effect.
3. **The Breathing Walls:**
- *Vertex Manipulation:* For each wall, modify the vertices of the geometry in a rhythmic pattern using a sine wave function. This will create the illusion of the walls subtly expanding and contracting.
- *Timing:* Use the `clock` object in Three.js to keep track of time and create a smooth, continuous animation.
4. **The Liquid Floor:**
- *Initial Setup:* Create a floor geometry with a solid material.
- *Interaction:* Add an event listener for mouse clicks. Use `Raycaster` to detect clicks on the floor.
- *Ripple Effect:* When a click is detected, apply a GLSL shader to the floor material to create a ripple effect emanating from the click point. This shader will use a sine wave function to distort the floor's surface normals, creating the appearance of water ripples.
5. **The Living Painting:**
- *Frame and Positioning:* Place a painting frame on another wall.
- *Procedural Patterns:* Create at least three different abstract patterns using either GLSL shaders or the canvas API. These patterns will be generated procedurally and can include shapes, colors, and animations.
- *Cycling:* Use a timer to cycle through the different patterns every 10 seconds, updating the texture or material of the painting.
6. **The Window to Nowhere:**
- *Positioning:* Place a window geometry on a third wall.
- *Shader Scene:* Create a dynamic, impossible deep space scene using a GLSL shader. This shader will generate swirling nebulae and stars, with animations that move independently of the room.
- *Integration:* Apply the shader to the window material to create the illusion of looking into deep space.
7. **User Interaction:**
- *Camera Controls:* Implement mouse controls to allow the user to look around the room. Use Three.js `OrbitControls` or similar to handle mouse input and camera movement.
- *Event Listeners:* Add event listeners for mouse clicks and movements to trigger the interactive elements (e.g., melting clock, liquid floor).
8. **Code Structure:**
- Use classes to encapsulate the different elements of the scene (e.g., `MeltingClock`, `BreathingWalls`, `LiquidFloor`, `LivingPainting`, `WindowToNowhere`).
- Comment the code thoroughly to explain the functionality and techniques used.

This HTML file creates a surrealist 3D room with all the requested features using Three.js and GLSL shaders. The code is structured into classes and methods for better organization and readability. Each surreal feature is implemented with appropriate techniques such as raycaster for interaction, vertex manipulation for breathing walls and melting clock, and shaders for the liquid floor and window to nowhere.Drag to resize
### Plan d'Action
As a surrealist artist channeling the dreamlike essence of Dalí, Magritte, and Ernst through code, I'll craft this interactive 3D room where physics bends to the subconscious. The base scene will be a minimalist room using Three.js: a PerspectiveCamera, OrbitControls for mouse look-around (but no movement, just rotation), and a WebGLRenderer. The room consists of a floor and four walls as PlaneGeometries, positioned accordingly. I'll structure the code with classes for each surreal feature (e.g., MeltingClock, BreathingWalls) to keep it modular and clean. All logic in vanilla JS, with Three.js loaded from CDN. Now, detailed plans for each feature:
1. **The Melting Clock (Homage to Dalí)**:
- Technique: Create a clock as a custom Mesh with a CircleGeometry for the face and LineSegments for hands/ ticks. Position it on one wall (e.g., front wall).
- Detection: Use raycasting from the camera to check if the user's gaze (center of view) intersects the clock mesh. In the animation loop, cast a ray from camera position through the center of the screen.
- Melting Effect: When ray hits, manipulate vertices in real-time. In the update loop, if looking, apply a distortion to each vertex: offset y-position downward based on a time-based sine function, amplified over time to simulate dripping. Use a "melt factor" that increases while looking and resets or decreases when looking away. This will deform the geometry dynamically without regenerating it each frame for efficiency. Comments will note vertex access via geometry.attributes.position.
2. **The Breathing Walls**:
- Technique: Each wall is a PlaneGeometry mesh with a basic material. To make them breathe, I'll modify vertices in the animation loop using a global time variable.
- Effect: For each wall's geometry, iterate over vertices and adjust their positions (e.g., z-offset for depth) with a sine wave: position.z += amplitude * Math.sin(time + vertex-specific offset). The offset can be based on vertex x/y to create organic waves. Amplitude is small for subtlety, and the rhythm is slow (e.g., period of 5-10 seconds). Since all walls share this, I'll encapsulate in a BreathingWalls class that updates all four meshes. This creates an unsettling, living room feel. Regenerate normals after modification for proper lighting.
3. **The Liquid Floor**:
- Technique: The floor is a PlaneGeometry with a custom ShaderMaterial using GLSL.
- Ripple Effect: On mouse click, use raycasting to find the intersection point on the floor. Store ripple data (position, start time, radius) in an array (support multiple ripples).
- Shader: Vertex shader displaces vertices based on distance from ripple centers, using a wave function (e.g., sin(distance - time * speed) * exp(-distance / decay)). Fragment shader can add watery coloring or reflections. Pass uniforms like time, ripple centers (as vec2 array), and count. In JS, update uniforms each frame and add new ripples on click. This keeps the floor solid-looking until interacted with, then reveals its liquid nature.
4. **The Living Painting**:
- Technique: The painting is a PlaneGeometry mesh on another wall (e.g., left wall) with a frame as a simple BoxGeometry border.
- Changing Subject: Use a CanvasTexture where I draw procedural patterns on a 2D canvas element. Cycle through at least three patterns every 10 seconds via setInterval: e.g., (1) swirling vortices with noise (Perlin-like via Math.random), (2) geometric fractals (recursive shapes), (3) abstract color blobs (gradient fills with randomness).
- Implementation: In a LivingPainting class, maintain a canvas, context, and pattern functions. Every 10s, clear canvas, generate new pattern, update texture (texture.needsUpdate = true). This is procedural and efficient, no shaders needed here to keep it simple, but could integrate one if desired.
5. **The Window to Nowhere**:
- Technique: The window is a PlaneGeometry "portal" on a third wall (e.g., right wall), with a frame like the painting.
- Deep Space Scene: Apply a ShaderMaterial with GLSL for a dynamic nebula/starfield. Vertex shader simple (pass UVs), fragment shader generates swirling colors using noise functions (e.g., fbm or simplex noise for clouds), time-based rotation/movement for swirling, and procedural stars as bright points.
- Independence: Update a time uniform in the animation loop to animate the shader independently of the room. This creates an "impossible" view that feels detached, enhancing surrealism. No raycasting needed; it's always visible through the window plane.
Overall Structure: HTML with <script src="https://cdn.jsdelivr.net/npm/three@0.132.2/build/three.min.js"></script>, then inline <script> for code. Init scene, camera, renderer, controls. Create room meshes. Instantiate feature classes, each with init() and update() methods called in animate(). Use requestAnimationFrame for loop. Add basic lighting (Ambient + Point). Handle window resize. Comments throughout for clarity.

Here’s the detailed Plan d’Action, feature by feature, before we dive into code:
1. Overall Scene Setup
• Create a Three.js scene, perspective camera, WebGLRenderer, and attach OrbitControls so the user can look around with the mouse.
• Build a simple “room” out of five planes (floor + 4 walls). Give each wall its own BufferGeometry so we can manipulate vertices independently.
• Maintain a `.update(delta)` method on each major element so we can animate them each frame.
2. Melting Clock
• Geometry: A simple circular ring + hour/minute hands, grouped and placed flush against one wall. Store its original vertex positions in an attribute.
• Raycasting: Each frame, cast a ray from the camera through the center of the view. If it intersects the clock’s mesh (using Three.js Raycaster), set a “melting” flag.
• Melting Shader/Vertex Manipulation:
– In JS (BufferGeometry), on each update when melting is active, iterate over the ring’s vertices that lie below a threshold (mid-height). For each:
• Compute a meltAmount = ease(timeLooking) * noise(x,z)
• Offset y downward by meltAmount * delta. Clamp so it never goes above original.
– When the user looks away, reverse the effect over time to let the clock “regain” its shape.
3. Breathing Walls
• Each wall has a BufferGeometry subdivided (e.g. 20×20 segments). Store original positions.
• In `.update(time)`, for each vertex:
newPos = originalPos + normal * sin(time * speed + wallIndex * phaseOffset) * amplitude
• Upload updated positions via `geometry.attributes.position.needsUpdate = true`.
4. Liquid Floor (Ripple Shader)
• The floor is a PlaneGeometry with many segments. Use a custom ShaderMaterial.
• Maintain an array of ripple sources: each has (x, z, startTime). On click, use a Raycaster to find intersection point on floor, push a new source.
• In the vertex shader: for each vertex, loop over ripple sources (up to a small max, e.g. 10):
float d = distance(vertex.xz, sourcePos);
float t = (uTime - sourceStart) * speed;
displacement += amplitude * sin(d * frequency - t) * exp(-d * decay);
position.y += displacement;
• Pass the ripple array as uniforms (positions + startTimes).
5. Living Painting
• A simple PlaneGeometry in a frame on another wall. The material is a ShaderMaterial or a dynamic CanvasTexture.
• Every 10 seconds cycle a uniform or redraw the canvas to choose one of three procedural patterns:
1) Animated noise (Perlin or simplex) in swirling shapes
2) Colorful Voronoi cells pulsing
3) Oscillating stripes with evolving colors
• The shader uses `mod(uTime, 30.0)` or a counter to switch patterns.
6. Window to Nowhere
• Another PlaneGeometry “window” on the third wall, also a ShaderMaterial.
• The fragment shader generates a deep-space scene:
• Fractal noise for nebula clouds, colored with a palette function
• Starfield: random white points and twinkling via a time-based flicker
• A subtle swirling velocity field animates the nebula.
• This shader is fed only by `uTime`; it doesn’t depend on camera or scene.
7. Structure & Boilerplate
• One single HTML file.
• Include Three.js and OrbitControls via `<script>` tags pointing to the official CDN.
• Define ES6 classes:
– SurrealRoom (initializes scene, camera, renderer, controls, lights, and elements; calls `.animate()`)
– MeltingClock, BreathingWall, LiquidFloor, LivingPainting, WindowScene
• In the animation loop:
1) Compute `delta` and cumulative `time`.
2) Update controls.
3) Raycast for clock.
4) Call `.update(time, delta)` on each element.
5) Render.
With this plan in place, we can proceed to implement the single-file HTML/JS containing all these classes, the scene setup, and the required shaders.Drag to resize
### Plan to Create an Interactive 3D Surrealist Room
To tackle this project, we will break down the task into smaller sub-tasks, focusing on each surreal feature individually. Here's a detailed plan for each component:
#### The Melting Clock
1. **Create the clock mesh**: Start by creating a simple analog clock mesh using Three.js. This will involve creating the clock face, hands, and possibly some decorative elements.
2. **Raycasting**: Use Three.js's built-in raycasting functionality to determine when the user's camera is looking directly at the clock. This will involve creating a raycaster and checking for intersections with the clock mesh.
3. **Vertex manipulation**: When the clock is in view, manipulate its vertices to create a melting effect. We can achieve this by using a sine or noise function to offset the vertices along the y-axis, creating a dripping effect. We'll need to update these vertices in real-time to create a smooth animation.
#### The Breathing Walls
1. **Create the walls**: Create the four walls of the room using Three.js. We'll use a simple plane geometry for this.
2. **Vertex manipulation**: Use a sine wave function to modify the wall vertices, creating a breathing effect. We'll offset the vertices along the z-axis (i.e., perpendicular to the wall surface) to create a subtle expansion and contraction effect. The sine wave will be animated over time to create a continuous, organic motion.
#### The Liquid Floor
1. **Create the floor**: Create the floor geometry using Three.js.
2. **Shader implementation**: Use a GLSL shader to create a ripple effect on the floor when the user clicks. We'll need to:
* Create a shader that distorts the floor geometry based on a ripple function.
* Use Three.js's `ShaderMaterial` to apply this shader to the floor mesh.
* Pass the mouse click position and time to the shader to animate the ripple.
3. **Raycasting**: Use raycasting to detect when the user clicks on the floor and pass the click position to the shader.
#### The Living Painting
1. **Create the painting frame**: Create a simple frame mesh using Three.js.
2. **Procedural patterns**: Create at least three different abstract, procedurally generated patterns using a GLSL shader or the canvas API. We'll need to:
* Create a shader or canvas context that generates these patterns.
* Use Three.js's `CanvasTexture` or `ShaderMaterial` to apply these patterns to a plane geometry inside the frame.
3. **Pattern switching**: Use JavaScript's `setInterval` function to switch between the different patterns every 10 seconds.
#### The Window to Nowhere
1. **Create the window**: Create a window mesh using Three.js, including a frame and a plane for the windowpane.
2. **Deep space shader**: Create a GLSL shader that generates a dynamic, impossible deep space scene with swirling nebulae and stars. We'll need to:
* Use noise functions and other shader techniques to create a realistic, swirling pattern.
* Animate the shader over time to create a sense of movement.
3. **Apply the shader**: Use Three.js's `ShaderMaterial` to apply this shader to the windowpane plane.
### Implementation
We will implement the above plan using a single HTML file, with vanilla JavaScript and the Three.js library loaded from a CDN. The code will be structured into classes for each surreal feature, ensuring it is clean, well-organized, and commented.
Now, let's proceed to writing the code.
Here is the code that implements the above plan:

This code creates a surrealist room with the requested features. The room is interactive, and the user can look around using the mouse. The clock melts when looked at, the walls breathe, the floor ripples when clicked, the painting changes patterns every 10 seconds, and the window shows a dynamic, impossible deep space scene.Drag to resize
# Surreal Interactive 3D Room - Implementation Plan
After analyzing the requirements, I'll create a comprehensive solution in a single HTML file. Here's my implementation strategy:
**Overall Architecture:**
- Use Three.js for 3D rendering and interaction
- Use GLSL for custom shading effects (floor/window/painting)
- Implement mouse look controls with OrbitControls
- Structure scene with separate objects (room, clock, window, painting, floor)
**Feature Implementation Details:**
1. **The Melting Clock**:
- Create a 3D cylinder primitive for the clock face
- Implement raycasting to detect when the camera is pointing at the clock
- Use vertex shader warping with time-based animations to simulate melting
- Add vertex displacement when observed with linear interpolation for smooth transitions
2. **Breathing Walls**:
- Create four planes forming the room walls
- Apply a vertex shader with sine-wave displacement along the normal vector
- Use a time uniform to create rhythmic pulsating motion
- Configure subtle amplitude for unsettling atmosphere
3. **Liquid Floor**:
- Create a plane with a custom shader material
- Implement raycasting to detect click position in world coordinates
- Use a ripple equation with exponential decay: `amplitude * exp(-decay*distance) * cos(frequency*distance - speed*time)`
- Pass click origin and timestamp to shader for ripple origin
4. **Living Painting**:
- Create a textured plane with GLSL fragment shader
- Cycle through 3 abstract patterns every 10 seconds:
1. Fractal noise landscape
2. Voronoi cellular pattern
3. Psychodelic color modulation
- Use time-elapsed logic to trigger pattern changes
5. **Window to Nowhere**:
- Create a plane with space scene fragment shader
- Implement procedural starfield with galactic nebula clouds
- Use 3D noise functions to create swirling cosmic patterns
- Animate independently with time uniforms
Now I'll implement the complete solution:

3. **Liquid Floor**: Interactive ripples generated from clicks with fading effect
4. **Living Painting**: Cycles through 3 abstract shader-based patterns
5. **Window to Nowhere**: Procedurally generated space nebula with animated stars
The experience is fully interactive with mouse look controls and fluid animations. All elements are contained in a single HTML file with no external dependencies beyond the Three.js library.Drag to resize
## Plan d'Action
Before diving into the code, let me outline my approach for each surreal feature:
### 1. The Melting Clock (Raycasting + Vertex Manipulation)
- Create a clock geometry using THREE.CylinderGeometry for the base and THREE.RingGeometry for the face
- Use THREE.Raycaster to detect when the camera is looking directly at the clock
- Store original vertex positions and create a melting animation by:
- Gradually moving vertices downward with varying speeds based on their Y position
- Adding some randomness and wave functions to create realistic dripping
- Smoothly interpolate between melted and original states
### 2. The Breathing Walls (Vertex Manipulation with Sine Waves)
- Create wall geometries with sufficient subdivisions for smooth deformation
- In the animation loop, modify vertex positions using sine waves:
- Apply different frequencies and phases to each wall for organic variation
- Use time-based functions to create rhythmic expansion/contraction
- Maintain wall connectivity at edges
### 3. The Liquid Floor (GLSL Shader + Click Detection)
- Implement mouse click detection using THREE.Raycaster to get world coordinates
- Create a custom GLSL shader that:
- Maintains an array of ripple centers and timestamps
- Calculates distance from each fragment to active ripple centers
- Uses sine waves with decay to create expanding ripple effects
- Blends multiple ripples when they overlap
### 4. The Living Painting (Canvas Texture + Procedural Generation)
- Create a canvas element and use 2D context for procedural art generation
- Implement three distinct pattern generators:
- Fractal noise patterns
- Geometric abstract compositions
- Flowing organic shapes
- Use setInterval to cycle through patterns every 10 seconds
- Update THREE.CanvasTexture dynamically
### 5. The Window to Nowhere (GLSL Fragment Shader)
- Create a plane geometry positioned as a window
- Implement a complex fragment shader featuring:
- Procedural nebula generation using noise functions
- Animated star field with twinkling effects
- Swirling motion using time-based transformations
- Deep space color gradients and atmospheric effects
Now, let's implement this surreal dream room:

This implementation creates a fully interactive surreal dream room with all the requested features:
1. **Melting Clock**: Uses raycasting to detect when looking at the clock and smoothly melts/unmelts the geometry
2. **Breathing Walls**: Applies sine wave transformations to wall vertices for organic movement
3. **Liquid Floor**: Implements ripple effects with GLSL shaders triggered by mouse clicks
4. **Living Painting**: Cycles through three procedurally generated patterns every 10 seconds
5. **Window to Nowhere**: Shows an animated deep space scene with swirling nebulae and twinkling stars
The experience feels like exploring a living, breathing surrealist painting where reality bends to dream logic!Drag to resize
**Action Plan for Building the Surreal 3‑D Room**
Below is a step‑by‑step design that maps every mandatory surreal element to concrete Three .js and GLSL techniques. The final deliverable will be a **single, self‑contained HTML file** that loads Three .js from a CDN, creates a minimalist room, and adds the interactive dream‑logic effects.
---
## 1. Overall Scene Structure
| Component | Purpose | Implementation |
|-----------|---------|----------------|
| **Scene, Camera, Renderer** | Core Three.js boilerplate | `new THREE.Scene();` <br> `new THREE.PerspectiveCamera(...);` <br> `new THREE.WebGLRenderer({ antialias:true })` with `canvas` added to the page. |
| **Room Geometry** | Four walls + floor | Each wall is a `PlaneGeometry` (large, thin) positioned and rotated to form a box. The floor is a `PlaneGeometry` placed at y = 0. |
| **Pointer‑Lock / Orbit Controls** | Mouse look around the room | Use `THREE.OrbitControls` (available in the same Three.js distribution) to rotate the camera when the user drags with the mouse. Controls are limited to yaw/pitch only (no panning). |
| **Lighting** | Simple ambient + directional light for visible shading | `scene.add(new THREE.AmbientLight(0x888888));` <br> `scene.add(new THREE.DirectionalLight(0xffffff,0.8).position.set(5,10,7));` |
All meshes will be grouped under a **Room** object for easy transformations and future extensions.
---
## 2. Surreal Feature #1 – *The Melting Clock* (Dalí homage)
### Goal
- When the camera looks directly at the clock, its geometry melts and drips down the wall.
- Melting stops when the gaze deviates.
### Techniques
| Step | Details |
|------|---------|
| **a. Clock Model** | Create a low‑poly analog clock: a thin cylinder for the face, two thin cylinders for hour/minute hands. Use `PlaneGeometry` for the dial texture (a simple drawn clock face via Canvas). |
| **b. Raycasting to Detect Gaze** | In each animation frame, cast a ray from the camera’s view direction (`camera.getWorldDirection`) and test intersection with the clock mesh using `THREE.Raycaster`. Store a boolean `isLookingAtClock`. |
| **c. Vertex Manipulation** | The clock will be built from a `PlaneGeometry` (for the face) whose vertices are stored in a custom buffer attribute named `originalPosition`. In the render loop, if `isLookingAtClock` is `true`, compute a melt factor based on time (e.g., `Math.sin(t*2) * 0.2`). For each vertex whose y‑coordinate is above a moving “drip line”, push it downwards proportional to the melt factor; also add a small horizontal jiggle for realism. When the user looks away, lerp the vertices back to their `originalPosition`. |
| **d. Dripping Effect** | After vertices have passed the wall boundary, generate tiny “drop” meshes (small spheres) that fall down under a simple gravity simulation and disappear after a short distance. These drops are added dynamically when a vertex crosses the floor plane. |
**Result:** Looking at the clock activates a procedurally deformed mesh that visually “melts” and leaves droplets on the floor.
---
## 3. Surreal Feature #2 – *Breathing Walls*
### Goal
- All four walls pulse in and out slowly, like a living organism.
### Techniques
| Step | Details |
|------|---------|
| **a. Wall Geometry** | Each wall is a `PlaneGeometry` with many divisions (e.g., 64×64) to give sufficient vertices for smooth deformation. |
| **b. Original Positions** | Store a `originalPosition` attribute (per vertex) once at creation. |
| **c. Sinusoidal Breathing** | In the render loop, compute a global time `t`. For each wall, calculate a radial offset: `offset = sin(t * breathSpeed + wallPhase) * breathAmplitude`. Apply this offset along the wall’s local normal (`planeNormal`) to the vertex positions: `position = original + normal * offset`. Since each wall has its own phase, they breathe asynchronously, adding an unsettling vibe. |
| **d. Updating Buffer Geometry** | Use `bufferGeometry.attributes.position.needsUpdate = true` after each frame. The operation is cheap because we only touch a few thousand vertices per wall. |
**Result:** The room’s container subtly expands and contracts, giving the impression of a living, breathing enclosure.
---
## 4. Surreal Feature #3 – *Liquid Floor (Ripple Shader)*
### Goal
- Clicking the floor generates expanding ripples as if the surface turned to water.
### Techniques
| Step | Details |
|------|---------|
| **a. Floor Mesh with ShaderMaterial** | The floor remains a `PlaneGeometry` (high subdivisions). Its material will be a custom `ShaderMaterial` that draws a base “solid” color and adds ripple displacement via a fragment shader. |
| **b. Uniforms** | Pass a `vec2 rippleCenter` (initially `(-1,-1)` meaning “no ripple”), a float `rippleTime`, and a float `rippleRadius` to the shader. |
| **c. Click Handling** | On `pointerdown` (or `mousedown`), cast a ray onto the floor; if intersected, record the hit point in world space and convert it to UV coordinates (0‑1 range). Reset `rippleTime = 0` and set `rippleCenter = uv`. |
| **d. Shader Logic** | In the fragment shader, compute distance from `rippleCenter`. Use a smoothstep function to create a sinusoidal wave that grows with `rippleTime`. Example: <br>`float d = distance(vUV, rippleCenter);` <br>`float wave = sin((d - rippleTime) * 12.0) * smoothstep(0.0, rippleTime, d);` <br> Multiply the wave by a small amplitude and use it to perturb the fragment’s normal (or color) to simulate a water ripple. |
| **e. Damping** | Increment `rippleTime` each frame; when it exceeds a set radius (`maxRippleRadius`) stop the ripple by resetting `rippleCenter = vec2(-1.0)`. The shader will simply output the solid floor color when no ripple is active. |
**Result:** A click creates a visually convincing expanding ripple across the floor, while the underlying geometry stays flat.

## 5. Surreal Feature #4 – *Living Painting (Changing Procedural Patterns)*
### Goal
- A framed painting on a wall cycles through at least three abstract procedural patterns every 10 seconds.
### Techniques
| Step | Details |
|------|---------|
| **a. Canvas‑Generated Texture** | Use an off‑screen `<canvas>` to draw a procedurally generated pattern every 10 s. The canvas provides a `CanvasTexture` that can be swapped into a `MeshStandardMaterial` for the painting. |
| **b. Pattern Types** | Implement three distinct pattern functions (e.g., a noisy Voronoi, a rotating gradient, and a simple sinusoidal wave grid). Each draws into the same canvas with `2d` API. |
| **c. Timing Loop** | Keep a timer (`clock.getElapsedTime()`) and when `elapsed % 10 < 0.02` (a brief window) call `drawPattern(nextPatternIndex)` and update the texture’s `needsUpdate = true`. Cycle the `nextPatternIndex` modulo 3. |
| **d. Frame Mesh** | The painting is a thin `PlaneGeometry` placed inside a simple wooden `BoxGeometry` frame. The frame uses a standard material; only the plane texture changes. |
**Result:** The painting continuously evolves, reinforcing the feeling of a living artwork.
---
## 6. Surreal Feature #5 – *Window to Nowhere (Deep‑Space Shader)*
### Goal
- Looking through the window shows a moving, impossible deep‑space scene independent of the room’s camera.
### Techniques
| Step | Details |
|------|---------|
|**a. Window Plane** | On one wall, place a `PlaneGeometry` sized like a window, but *not* oriented toward the camera (it stays upright, just like a regular wall). |
|**b. Render‑to‑Texture (Optional)** | Rather than drawing a separate scene, embed the whole deep‑space animation directly in the window’s fragment shader. This is lighter than a secondary render pass. |
|**c. ShaderMaterial (Space)** | Provide a shader that generates procedural nebulae: combine layered Perlin noise (implemented in GLSL), a star field via pseudo‑random point generation, and swirling motion via time‑varying rotation matrix. |
|**d. Uniforms** | Pass `time` and `resolution` to the shader. The space animation loops endlessly and moves regardless of the room camera. |
|**e. Depth Decoupling** | The window material uses `depthWrite: false` and `transparent: true` to avoid z‑fighting with the wall. |
|**f. Optional Background Pass** | If needed, we could create a separate `Scene` with a large sphere surrounding the camera, render it to a `WebGLRenderTarget`, and display that texture on the window plane. Simpler to stay in‑shader. |
**Result:** The window acts as a portal into an endlessly shifting starfield, reinforcing the surreal “impossible depth”.

## 7. Interaction & Animation Loop
| Phase | Action |
|-------|--------|
| **Update Time** | `let elapsed = clock.getElapsedTime();` |
| **Raycast Clock** | Detect gaze; set melt flag. |
| **Melting Logic** | Adjust clock vertex positions based on melt flag. |
| **Wall Breathing** | Apply sine‑based offset to each wall’s vertices. |
| **Ripple Update** | Increment `rippleTime` uniform; the shader self‑handles ripple expansion. |
| **Painting Switch** | Check timer modulo 10 s, regenerate canvas pattern. |
| **Space Shader** | Update `time` uniform on the window shader. |
| **Render** | `renderer.render(scene, camera);` |
All updates will run inside a `requestAnimationFrame` loop. Since all geometry is pre‑created, modifications are limited to buffer‑attribute updates and uniform tweaks—keeping perf smooth on a modern browser.
---
## 8. Code Organization & Cleanliness
- **Class `Room`** – constructs floor, walls, and stores references for breathing.
- **Class `Clock`** – builds the analog clock, holds original vertex positions, methods `updateMelt(flag, time)`.
- **Class `Floor`** – builds floor mesh with RippleShaderMaterial, method `handleClick(uv)` to start ripple.
- **Class `Painting`** – manages canvas texture and pattern cycle.
- **Class `Window`** – creates the space shader plane and updates its time uniform.
- **Main script** – sets up scene, controls, renderer, attaches event listeners (click, pointermove), runs the animation loop.
Each class will be heavily commented, explaining attribute setup, GLSL snippets, and the math behind the surreal effects.
---
## 9. Asset & Library Loading
- Load **Three.js** via `<script src="https://cdn.jsdelivr.net/npm/three@0.165.0/build/three.min.js"></script>`.
- Load **OrbitControls** from the same CDN (`examples/js/controls/OrbitControls.js`).
- No external dependencies beyond the CDN scripts—everything else is native JavaScript or GLSL embedded in the HTML.
---
### Summary
By combining:
- **Raycasting** for gaze detection,
- **Vertex displacement** for melting and breathing,
- **Custom shader materials** for fluid ripples and impossible space,
- **Canvas procedural textures** for the living painting,
the final single‑HTML file will deliver a fully interactive, dream‑logic‑infused room that feels like stepping inside a surreal painting. The plan respects all constraints, uses only vanilla JS and Three .js from a CDN, and keeps the code modular and well‑commented for readability.Drag to resize
Below is my detailed plan to implement the surreal interactive 3D room. I'll break it down feature by feature, explaining the key techniques, before providing the full, self-contained HTML file. This plan ensures the code is clean, well-structured using classes for different elements (e.g., separate classes for the clock, walls, floor, painting, and window), and adheres to the constraints. We'll use Three.js loaded from a CDN, vanilla JavaScript, and GLSL shaders where specified.
### Plan for Implementation
1. **Melting Clock (Homage to Dalí):**
- **Key Techniques:** I'll use Three.js's Raycaster to detect when the camera is looking directly at the clock. In the animation loop, I'll perform a raycast from the camera's position in the direction it's facing. If the ray intersects the clock mesh, I'll manipulate its vertices to simulate melting. This involves accessing the geometry's vertices array and applying a dynamic offset to each vertex's y-position (to make it "drip" downward). The offset will be based on the vertex's original y-position and a time-based factor that increases when the clock is in view, creating a melting effect. When the ray no longer intersects, I'll stop the deformation by resetting or pausing the offsets. To make it efficient, I'll use a custom vertex shader for real-time manipulation instead of modifying vertices in JavaScript every frame, which could be performance-intensive.
- **Structure:** I'll create a `MeltingClock` class that handles the clock's geometry (e.g., a cylinder for the clock face and lines for hands), sets up the raycaster, and updates the shader uniforms in the animation loop. This keeps the logic modular.
2. **Breathing Walls:**
- **Key Techniques:** For the walls, I'll use PlaneGeometry and modify their vertices directly in the animation loop to create a breathing effect. A sine wave function (e.g., `Math.sin(time * speed)`) will be applied to each vertex's position along the wall's normal (outward direction), causing the walls to expand and contract rhythmically. This will be subtle, with a small amplitude to avoid distortion. I'll update the vertices every frame but ensure performance by only modifying the geometry once per frame and using `geometry.attributes.position.needsUpdate = true` to notify Three.js of changes. To add an organic feel, I'll incorporate a slight random offset per vertex using a noise function.
- **Structure:** A `BreathingWalls` class will manage the four wall meshes, store their geometries, and handle the vertex updates in a dedicated method called from the main animation loop. This encapsulates the breathing logic.
3. **Liquid Floor:**
- **Key Techniques:** The floor will start as a simple PlaneGeometry with a basic material. To create the ripple effect, I'll use a custom GLSL fragment shader that simulates water distortion. The shader will take uniforms for time, click position, and ripple strength. When the user clicks, I'll use raycasting to determine the 3D intersection point on the floor, then pass that as a uniform to the shader. The shader will use a ripple algorithm (e.g., based on sine waves emanating from the click point) to distort the texture or color over time, fading out naturally. This ensures the effect is interactive and performant, as shaders run on the GPU.
- **Structure:** A `LiquidFloor` class will handle the floor mesh, set up the custom ShaderMaterial, and listen for mouse click events to update the shader uniforms. The class will integrate with the main scene's event listeners.
4. **Living Painting:**
- **Key Techniques:** On a wall, I'll place a PlaneGeometry as the painting frame. For the procedurally generated patterns, I'll use a custom GLSL fragment shader that changes based on a time uniform. The shader will cycle through at least three abstract patterns (e.g., one based on Perlin noise for cloudy shapes, another on fractals like the Mandelbrot set for intricate designs, and a third using simple color gradients with noise). Every 10 seconds, I'll update a uniform in the shader to switch patterns, using JavaScript's `setInterval` to trigger the change. This procedural approach ensures the patterns are generated on the fly without external assets.
- **Structure:** A `LivingPainting` class will manage the painting mesh and its ShaderMaterial. It will include a method to cycle patterns, called via a timer, keeping the logic self-contained.
5. **Window to Nowhere:**
- **Key Techniques:** For the window, I'll use a PlaneGeometry on a wall with a custom GLSL fragment shader to render a dynamic deep space scene. The shader will simulate swirling nebulae and stars using noise functions (e.g., simplex noise for organic movement) and time-based animations. Uniforms for time will drive the animation, creating an independent, infinite scene that doesn't rely on the room's camera. This will be achieved entirely in the shader to keep it efficient and surreal, with stars as point sprites and nebulae as colorful, flowing distortions.
- **Structure:** A `WindowToNowhere` class will handle the window mesh and its ShaderMaterial, updating the time uniform in the animation loop for smooth animation.
**Overall Scene Setup:**
- The main script will set up a Three.js scene, PerspectiveCamera, WebGLRenderer, and OrbitControls for mouse-based camera rotation.
- I'll use classes for each feature to organize the code, with a central `App` class to initialize everything, add objects to the scene, and handle the animation loop.
- All GLSL shaders will be defined as strings within the JavaScript code for self-containment.
- The HTML file will include the Three.js CDN link and all scripts in a single <script> tag.
This plan ensures a cohesive, interactive experience while meeting the technical constraints. Now, here's the full HTML file.
