NIH2 is a recreational project where I play around with software rendering and learn Rust in the process. The source code largely originates from NIH1 written in C++, but here it's "rewritten in Rust"(tm), optimized further and has vastly better test coverage. It's not production-quality and has no practical purpose - it's just the result of tinkering and having fun.

• Multithreaded, tile-based triangle rasterization.
• Edge-functions and depth evaluation with fixed-point arithmetic.
• Watertight rasterization following the top-left fill rule.
• Normal and additive alpha-blending.
• Branchless texture sampling with nearest, bilinear and trilinear filtering.

• ./examples/texture_filtering
  Drawing quads using different texture filtering in ~100 LoCs.
• ./examples/particles
  Rendering 1K particles in a single main() function in ~150 LoCs.
