X-Wing flying
Prompt
Create a 3D recreation of the Death Star trench run scene from Star Wars using Three.js. The Death Star should be detailed and procedurally generated, with gun turrets that shoot at the ship as it flies through. The X-Wing should fly automatically on autopilot in an intelligent and engaging way. The scene should feature infinite looping, a responsive design, and a minimum of 15 unique seconds of high-quality animation. It should be detailed, cinematic, aesthetic, and visually interesting. The environment should include procedural generation, collision detection, particle and laser effects, performance optimizations, and a pathfinding system with obstacle avoidance.

This Death Star trench run recreation features:
**Core Features:**
- Detailed procedurally generated Death Star surface with trench
- Intelligent X-wing autopilot with smooth pathfinding
- Turrets that track and shoot at the X-wing
- Particle effects for engines and explosions
- Laser effects with collision detection
- 15+ second looping animation
- Responsive design
**Visual Elements:**
- Cinematic camera following the X-wing
- HUD with altitude and speed display
- Engine trails and particle effects
- Dramatic lighting and shadows
- Detailed 3D models for X-wing and turrets
**Technical Implementation:**
- Obstacle avoidance pathfinding system
- Performance optimizations with object pooling
- Smooth interpolation for flight movement
- Collision detection for lasers
- Procedural generation of surface details
- Infinite looping with seamless transitions
The X-wing flies through the trench automatically, banking and weaving around obstacles while turrets track and fire at it, creating an engaging and cinematic experience that captures the iconic Star Wars scene.Drag to resize
# Death Star Trench Run Simulation
I'll create a cinematic 3D recreation of the Death Star trench run using Three.js with all the requested features. This will include a procedurally generated Death Star trench, X-Wing fighter with autopilot, gun turrets with targeting, and visual effects.

Here is a 3D recreation of the Death Star trench run.
The scene features a procedurally generated, infinitely looping trench with detailed surfaces. An X-Wing flies on a dynamic autopilot, navigating the trench and actively dodging large obstacles. Enemy turrets track the ship and fire lasers, triggering explosions on impact. The animation is enhanced with cinematic camera work, particle effects, and post-processing bloom for a visually rich experience.
