All right guys! Let's start posting and sharing links useful for guys who want to get into physical simulation in computer graphics!!! I'll start below!!!

Made some more progress with my river render. Switched from using advected textures to Stefan Jeschke's Siggraph 2018 Wave Profile ideas. Looks much richer! #screenshotsaturday

A map from the unit square to the unit circle, without trigonometry, that I found in this paper arxiv.org/ftp/arxiv/pape… . I reduced and simplified to just v = maxcomp(abs(v))*normalize(v) Not for sampling, but great for geometry. Presumably works in 3D! shadertoy.com/view/3dsSWs

Just today... I found a stack of old tapes and discs that we filmed from past fighting game events (early 2000s). Check out this alternate viewpoint from one of the legendary moments in competitive gaming history... youtu.be/Kg1xPOUn7vQ

the old lfo trick to get stable sin & cos waves still amazes me, especially as it looks like a complex multiplication done wrong: c-=a*s; s+=a*c; that's it! start with c=1,s=0, a small constant. fp errors cancel, stable forever. note no temp copy of c/s in update!feels like magic

Not wearing pants on a zoom call is frustum culling

20 years later, this is still my favorite uv-packing algorithm www-ui.is.s.u-tokyo.ac.jp/~takeo/papers/…

Nobody knows how much games cost to develop, how they’re developed, and how game design works.

I'm all for uneccesary displays of technology, but these $5 mini cups of coffee from an off the shelf coffee maker are going to need a better gimmick than this robotic arm in Downtown San Francisco.
