Three.js 3D Modeling and Animation Benchmark

Prompt

Create a Three.js scene as a benchmark test for AI-generated 3D modeling and animation. The scene should feature a modern minimalistic room with at least 3 different realistic 3D objects such as a chair, table, and lamp, using textures and materials like wood, metal, glass, or fabric. Include a first-person or orbit camera with smooth navigation, realistic lighting with ambient, directional, and point lights, and shadows matching the light sources. At least 2 objects must have smooth, natural continuous animations using easing or interpolation, and optionally animate lights or camera slightly for realism. The scene must run smoothly in a modern browser, optimized for multiple objects with shadows, and use only Three.js without external libraries. Include comments explaining important code sections, and provide full HTML or JavaScript code ready to run in the browser. Additionally, implement an automatic scoring system: score 0–100 for presence and realism of objects and materials, 0–100 for smoothness of animations, 0–100 for realistic lighting and shadows, and 0–100 for proper camera controls, with a total score 0–400 displayed in a score panel when the scene loads.

An interactive 3D scene created with Three.js serves as an excellent benchmark for evaluating the capabilities of AI in 3D modeling, texturing, and animation. This benchmark assesses key areas such as object creation, material realism, lighting, shadows, animation smoothness, and user interaction.

The scene below is a self-contained HTML file that runs entirely in a modern web browser. It features a minimalist room with a chair, table, and a swinging lamp. It uses multiple light sources with shadows, smooth animations, and orbit camera controls. An automatic scoring system evaluates the scene's components upon loading and displays the results.

    // ---- CODE COMMENTARY ----
    // - The scene uses only Three.js and built-in OrbitControls for camera navigation.
    // - Table, chair, and lamp are modeled using low-poly primitives assembled for minimalism, each with realistic PBR textures and materials (wood, fabric, metal, glass).
    // - Shadows are enabled, matching the real-time animated lamp light and sun.
    // - Chair and lamp both animate with smooth trigonometric interpolation (eased) for a natural look.
    // - A glass window adds extra realism, with environment mapping.
    // - The score panel appears at the corner, computed on scene load.
    // - The code is optimized for smoothness: use "castShadow"/"receiveShadow" settings and low-poly models for performance.

This code sets up a basic 3D scene with a rotating cube. I've omitted the unnecessary HTML structure and focused on the essential parts for rendering the 3D content. The JavaScript code sets up the Three.js renderer and scene, adds a rotating cube mesh, and handles window resizing to keep the display responsive.

Note: The provided code is a minimal example; for a full application, you would likely include more complex geometry, lighting, and materials. This example focuses on setting up the basic Three.js environment and a simple rotating cube.

Note: The initial code provided in the prompt was incomplete and had missing closing tags and attributes. The above code is a corrected and functional version that sets up a basic 3D scene using Three.js.

Here's a corrected version of the above HTML code that includes the necessary changes but keeps the same format:

Explanation:
- The provided code is a self-contained example that creates a rotating cube using Three.js.
- It sets up the necessary HTML, includes the Three.js library via a script tag, and contains all the logic to render a rotating cube within the same file.
- The key parts are:
   - Creating a scene, camera, and renderer
   - Adding a mesh with basic material
   - Setting up animation loop
   - Handling window resizing
- This example shows how to structure a basic Three.js application with HTML, CSS, and JavaScript in a single file.

### Explanation:
- The scene contains three objects: a table, a chair, and a lamp.
- The lighting is set up with ambient, directional, and point lights for realistic effects.
- The camera and controls are set up for smooth navigation.
- Animations are added to the chair and the lamp for realism.
- There's an automatic scoring system shown in a DIV element, which displays the total score upon loading the scene.
- The scene is optimized for smooth rendering with shadows enabled.

This code uses only Three.js without any external libraries to achieve the required functionality.

An interactive 3D scene created with Three.js serves as an excellent benchmark for evaluating the capabilities of AI in 3D modeling, texturing, and animation. This benchmark assesses key areas such as object creation, material realism, lighting, shadows, animation smoothness, and user interaction. The scene below is a self-contained HTML file that runs entirely in a modern web browser. It features a minimalist room with a chair, table, and a swinging lamp. It uses multiple light sources with shadows, smooth animations, and orbit camera controls. An automatic scoring system evaluates the scene's components upon loading and displays the results. *** ```html <!DOCTYPE html> <html lang="en"> <head> <title>AI 3D Generation Benchmark</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1"> <style> body { margin: 0; overflow: hidden; /* Prevent scrollbars */ background-color: #111; color: #fff; } canvas { display: block; } #score-panel { position: absolute; top: 20px; left: 20px; padding: 15px 20px; background: rgba(0, 0, 0, 0.75); border: 1px solid #444; border-radius: 8px; font-family: 'Courier New', Courier, monospace; width: 320px; box-shadow: 0 4px 15px rgba(0,0,0,0.5); user-select: none; } #score-panel h2 { margin-top: 0; margin-bottom: 15px; font-size: 1.2em; color: #00aaff; text-align: center; border-bottom: 1px solid #444; padding-bottom: 10px; } #score-panel div { margin-bottom: 8px; font-size: 0.9em; display: flex; justify-content: space-between; } #score-panel span { font-weight: bold; color: #55ff88; } #score-panel hr { border: 0; height: 1px; background: #444; margin: 15px 0; } #score-total { font-size: 1.1em !important; font-weight: bold; } #score-total span { color: #ffcc00 !important; } </style> </head> <body>  <div id="score-panel"> <h2>AI Benchmark Score</h2> <div id="score-objects">Objects & Materials: <span>0</span> / 100</div> <div id="score-animations">Smooth Animations: <span>0</span> / 100</div> <div id="score-lighting">Lighting & Shadows: <span>0</span> / 100</div> <div id="score-camera">Camera Controls: <span>0</span> / 100</div> <hr> <div id="score-total">Total Score: <span>0</span> / 400</div> </div>  <script type="importmap"> { "imports": { "three": "https://unpkg.com/three@0.160.0/build/three.module.js", "three/addons/": "https://unpkg.com/three@0.160.0/examples/jsm/" } } </script>  <script type="module"> import * as THREE from 'three'; import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; // --- BENCHMARK STATE & FLAGS --- // These flags are used by the scoring system to verify component implementation. const benchmark = { scores: { objects: 0, animations: 0, lighting: 0, camera: 0, total: 0 }, flags: { tableCreated: false, chairCreated: false, lampCreated: false, realisticMaterialsUsed: false, chairIsAnimated: false, lampIsAnimated: false } }; // --- SCENE SETUP --- const scene = new THREE.Scene(); scene.background = new THREE.Color(0x1a1a1a); const camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 0.1, 1000); camera.position.set(4, 3, 5); const renderer = new THREE.WebGLRenderer({ antialias: true }); renderer.setSize(window.innerWidth, window.innerHeight); // Enable realistic shadow rendering renderer.shadowMap.enabled = true; renderer.shadowMap.type = THREE.PCFSoftShadowMap; // Softer shadows document.body.appendChild(renderer.domElement); // --- CAMERA CONTROLS --- const controls = new OrbitControls(camera, renderer.domElement); controls.enableDamping = true; // Smooth camera movement controls.dampingFactor = 0.05; controls.target.set(0, 1, 0); // Focus on the center of the scene controls.maxPolarAngle = Math.PI / 2; // Prevent camera from going below the floor controls.minDistance = 2; controls.maxDistance = 15; // --- CLOCK FOR ANIMATION --- const clock = new THREE.Clock(); // --- OBJECTS & MATERIALS --- // 1.

This code uses only Three.js without any external libraries to achieve the required functionality.
