A real-time interactive raymarching renderer built with wgpu, written in Rust and WGSL. This project demonstrates distance field rendering techniques through raymarching.
Raymarching is a rendering technique that creates 3D scenes by "marching" along a ray until hitting a surface defined by mathematical distance functions. This approach enables complex visual effects that would be difficult to achieve with traditional polygon rendering.
- Interactive Camera Control: Rotate the camera by clicking and dragging the mouse
- Distance Field Primitives: Spheres, boxes, and planes with smooth blending
- Dynamic Lighting & Shadows: Soft shadows and diffuse lighting
- Raymarched Reflections: Reflections with variable quality
- Material System: Different materials with unique visual properties
- Animated Objects: Dynamic movement of scene elements
- Customizable Performance: Toggle FPS capping with the
Fkey - User-Controlled Movement: Control object position using W/S keys
- Built with wgpu for cross-platform GPU access
- Shader code written in WGSL (WebGPU Shading Language)
- Leverages Signed Distance Fields (SDFs) for scene representation
- Implements smooth object blending with special material transitions
- Uses efficient ray marching with adaptive stepping
