A simple 3D software rasterizer built from scratch in Lua using LÖVE2D. No GPU acceleration—just pure CPU rendering to understand how 3D graphics work.
- Triangle rasterization using edge functions and barycentric coordinates
- Perspective projection with configurable field of view
- Z-buffering for correct depth sorting
- Perspective-correct interpolation for depth values
- FPS camera with mouse look (yaw/pitch) and WASD movement
- 3D transformations with rotation matrices
This is a learning project, so it intentionally lacks:
- ❌ Textures
- ❌ Lighting (Phong, Blinn-Phong, etc.)
- ❌ Backface culling
- ❌ View frustum clipping (only near plane clipping implemented)
- ❌ Anti-aliasing
If you want to understand how everything works and/or want to recreate this simple rasterizer on your own, I've made a with that purpose.
