History

While working with Robert Strickland on open-sourcing GemRay, which is now available here, I started playing around with trying to do the same in the browser. I have wanted to use WebGPU for a while, so this seemed like a good opportunity. I vibed a prototype in a few days, then spend a few more weeks polishing the edges.
