I'd like to talk to you about ray tracing. Have an algo that would be incredibly fast in hardware. I think I may have tried integer math at one time.

>> The AR350 ray-tracing chips process 66 million ray-triangle intersections per second per core.

I was doing 1.5 million Ray's per second against scenes with 100,000 polygons back then on an AMD64.

Acceleration structures are everything. Traversing them quickly and having dynamic updates is hard.
