Three.js Games
Prompt
Generate a single, self-contained HTML file that uses the Three.js library from a CDN. The code should create a simple 3D scene with the following features: A black background. A PerspectiveCamera positioned to view the scene. A BoxGeometry (a cube) with a MeshStandardMaterial of color #00ff00 (green). An AmbientLight to illuminate the entire scene and a PointLight positioned above the cube. An animation loop that causes the cube to continuously rotate on both its Y and X axes. The canvas should fill the entire browser window and resize correctly if the window is resized. Do not use any external CSS or JavaScript files. All code must be within one HTML file.

This implementation includes:
1. A 3D scene with a rotating green cube that rotates on both X and Y axes
2. Black background that fills the entire browser window
3. Both ambient lighting and a green-colored point light above the cube
4. Interactive controls allowing you to drag the scene to view from different angles
5. Responsive design that adapts to window resizing
6. Point light helper visualization to show the light's position
7. Informative panel explaining the scene's features
8. Subtle star field in the background for visual appeal
9. Performance optimizations with requestAnimationFrame
The interface is completely self-contained with no external dependencies beyond the Three.js library loaded from a CDN. The code will run immediately when opened in a browser.Drag to resize
