A shader-based software rasterizer written from scratch in C89 with minimal dependencies, featuring PBR, IBL, shadow mapping, and skeletal animation. It ships as a cross-platform 3D model viewer with orbital camera controls and a PBR material inspector.

Use cases

• render 3D models without a GPU or graphics API
• learn how a software rasterizer works internally
• study PBR and image-based lighting implementation
• view glTF-style PBR materials with a material inspector
• explore skeletal animation and shadow mapping in pure C
• use as a reference for writing a renderer from scratch

When to choose

• you want a minimal-dependency, CPU-only 3D renderer
• you are learning graphics programming and want readable C89 source
• you need a cross-platform viewer with prebuilt binaries
• you want to study PBR, IBL, or shadow mapping implementations

When to avoid

• you need high-performance GPU-accelerated rendering
• you want a production rendering engine or game engine
• you need a library API to embed in your own application
• you require modern C tooling or extensive documentation
