Software occlusion culling in Block Game
My GPU is the integrated Radeon Vega 8 that comes with my AMD Ryzen 7 5700G CPU. I tell you this so you know that my workstation is not a graphical computing powerhouse. It is, in fact, quite weak. To...

New Method Is the Fastest Way To Find the Best Routes | Quanta Magazine
A canonical problem in computer science is to find the shortest route to every point in a network. A new approach beats the classic algorithm taught in textbooks.

I gave an internal talk at UCSD last year regarding "novelty" in computer science research. In it I "debunked" some of the myth people seem to have about what is good research in computer science these days. People seemed to like it, so I thought I should share.

I got the first post about direct lighting material occlusion up on my blog. On this one I go over the commonly used micro-occlusion approach and its limitations, and I start digging into micro-shadowing as an improvement.

I'm just saying - the promise of C1 and sometimes C2 is... not actually true in general, and it's a giant pain in the arse to make it true. That's my experience anyway.

learned today that boost.polygon has no dependencies on the rest of boost, and it can do a 2D Voronoi diagram for line segments, which means it can be used to find the max-inscribed circle of a polygon (which is much harder than min-containing circle!). And it's quite fast, too.

Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable…
In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!
