Softrast is a software rasterizer developed as a freetime project as an excersise in API design, optimization and low-level graphics.
The project is written in C for the most part, with some components written in C++ because of dependencies.
Following is a list of features of SoftRast:
- Sub-pixel and sub-texel correct rendering
- Perspective correct texture mapping
- Support for trilinear filtering
- Cross-platform support*
- SOA math library (/w SSE & AVX versions)
(* The software rasterizer, model loader and texture loader are cross-platform, only the actual rendering API initialization is not cross-platform)
The following table outlines a subset of tasks remaining:
| Task description | Status | Comment |
|---|---|---|
| AABB frustum culling | Work in progress | Working but appears to have some failure cases |
| Implement scene graph | TODO | Currently more of a scene array than a scene graph |
| Rasterizer cleanup | TODO | |
| Rasterizer optimization | TODO | Outline filling and rasterization are far slower than they should ideally be |
| Lighting | TODO |
