2019/08/08 - Project still needs a lot of work and I haven't worked on it in a while, but I need to open-source this repo for reasons.

• Currently: 3.2 million rays/second
• Multi-threaded tile-based rendering
• Bounding Volume Hierarchy (BVH) as an acceleration structure
• Procedural texturing
• Wavefront OBJ file parsing and rendering
• Lambertian BRDF
• Stratified sampling
• Math (vectors, matrices), high-resolution timing, memory arena allocator and more via raywan/rw
