## features
- Very fast, small and efficient.
- Uses only integer math (32bit).
- No dependencies (uses only stdint standard library), extremely portable.
- Single header, KISS.
- Pure C99, tested to run as C++ as well.
- Still flexible -- pixels are left for you to draw in any way you want with a custom fragment-shader like function.
- Triangles provide barycentric coordinates, thanks to which practically anything that can be achieved with OpenGL can be achieved (texturing, shading, normal-mapping, transparency, PBR, shadow mapping, ...).
- Tested on multiple platforms (PC, Arduboy, Pokitto, Gamebuino META).
- Many compile-time options to tune the performance vs quality.
- Well commented and formatted code.
- Completely free of legal restrictions, do literally everything you want.
## limitations
- Though performance is high, due to multiplatformness it can't match platform-specific rasterizers written in assembly.
- Proper near-plane culling (subdividing triangles) is missing. You can either cull whole triangles completely or "push" them by the near plane. These options are okay when drawing a models not very close to the camera, but e.g. 3D environments may suffer from artifacts.
- Seeing buggy triangles flashing in front of the camera? With the limited 32bit arithmetic far-away things may be overflowing. Try to scale down the scene. If you also don't mind it, set `S3L_STRICT_NEAR_CULLING` to `1` -- this should probably solve it.
