Mikko Mononen @mikkomononen.bsky.social · 04/05/2025I came across this old presentation while searching for non-uniform scaling for SDF rendering. Has anyone put that in practice? www.essentialmath.com/GDC2015/VanV...essentialmath.com 221
Craig Reynolds @craigreynolds.bsky.social · 04/05/2025In 1998 I did pre-production tests for herds in “Spirit.” To get horses to pack closely enough I could not model them as disks so tried using ellipses. I was able to test for collisions by a similar trick of transforming into a space where the ellipse was a circle, and using a 2d distance test. 220
noah witherspoon @mahalis.bsky.social · 04/05/2025I’ve tried it for the basic ellipse case—as the presentation notes the method breaks down when you get farther in/out from the edge (e.g. for shadows/glows) but for antialiasing it seemed to work well 100
