Three.js Interactive 3D Light and Shadow Playground
Prompt
Create an interactive 3D scene with Three.js where users can manipulate different light sources (directional, point, spot) and see real-time shadow effects on geometric objects. Include controls to adjust light position, intensity, color, and shadow properties.

This interactive Three.js playground demonstrates different types of lighting and shadow effects in 3D space. Users can manipulate three distinct light sources: directional light (simulating sunlight), point light (omnidirectional light source), and spot light (focused beam).
Key Features:
- Real-time manipulation of light position, intensity, and color
- Interactive shadow controls including resolution and bias adjustment
- Multiple geometric objects showcasing different shadow interactions
- Visual helpers showing light source positions
- Animated objects with subtle floating motion
- Responsive design that works on various screen sizes
Learning Points:
- Understanding different Three.js light types and their properties
- Shadow mapping implementation and optimization
- Real-time parameter adjustment with lil-gui controls
- Object-material interaction with different light sources
- Basic 3D scene setup with camera controls
The playground provides immediate visual feedback as users adjust parameters, making it an excellent educational tool for understanding 3D lighting fundamentals in real-time graphics.
