Software Rasterizer

Features:

• Multi-threaded tile binning architecture using SPMD paradigm
• AVX-512 SIMD that rasterizes triangles in 4x4 groups of pixels.
• Triangle clipping and guard-band clipping
• Mip-mapped bilinearly filtered texturing.
• 28.4 fixed-point subpixel rendering
• Renders complex scenes (1mil+ triangles) at a stable framerate

Below is a clip of a scene with ~900k triangles rendering with a frame time of ~10 milliseconds (~100 frames per second), captured on a Ryzen 9 7950x.

Build instructions

Currently only builds on Windows, MSVC or Clang is required. Running build release will by default try to build with MSVC, to build with Clang use build clang release
