Adding Meshes, BVHs, and Photon Mapping to My Browser Ray Tracer
The follow-up to the ray tracer refactor: Stanford bunnies, CPU photon mapping, world-space caustics, and a lot of renderer debugging.
Refactoring My Ray Tracer: From Broken to WebGPU Path Tracing
One character broke eight years of rendering. Codex fixed it, added Monte Carlo path tracing, and a WebGPU backend that's roughly 10x faster than CPU workers.
AOS: An Agent Operating System
Building a research prototype where agents collaborate through runtime primitives—artifacts, IPC, capabilities, and scheduling.
