Rasterator
What is it?
A Real-time, C++ toy software rasterizer created for understanding the graphics pipeline.
Features
- Near-complete implementation of the graphics pipeline
- Interactive framerates
- Depth buffering
- Perspective-correct vertex attribute interpolation
- OpenMP multithreading
- Texture mapping
- Bilinear texture filtering
- Cross platform (Windows, macOS, Linux, Emscripten)

Building
Windows/macOS/Linux
Recursively clone the repository and use CMake to generate a project of your choice.
Emscripten
Make sure to have the Emscripten SDK installed. Then use CMake with the Emscripten toolchain to generate a makefile (or MinGW makefile on Windows).
NOTE: Emscripten build is pretty slow, so use a lower resolution.
Roadmap
- SIMD Acceleration (SSE/AVX)
- Normal mapping
- Specular mapping
- Trilinear texture filtering
