Parallel software rasterizer written in C++.
Above scene (~35k triangles) renders in 60fps at 1920 x 1080 resolution on AMD Ryzen 5 3600 CPU.
- rendering with or without depth buffer
- drawing with or without index buffer
- programmable shaders (at compile time with C++ templates)
- multithreaded (each thread renders one vertical slice of the image)
- ability to specify viewport dimensions and offset (to render to only part of the image)
- loading meshes and textures
- sutherland-hodgman and front triangle clipping
- configurable alpha blending
- configurable depth test
- deffered rendering is possible and accelerated with specialized method for screen quad rendering
- rendering to screen or texture
