HN discussionCompletely disagree - convex collision detection is a neatly solved problem. SAT [0] is implementable in a couple of hours, and GJK [1] is a really neat algorithm that takes a ltitle more than SAT to implement. For optimising collision detection there's some spatial partitioning [2] algorithms that work really well. The gnarly stuff comes in when you're trying to figure out contact points and impulse responses and a…

HN discussionThere is another interesting application for dithering that I've read about in the recent Uncharted 4 Brain Dump (Ctrl-F for "Dithering") here https://redd.it/4itbxq : Use dithering instead of alpha blending to fade out close objects. Alpha blending can be quite expensive while dithering just omits pixels. The result looks like this: http://allenchou.net/wp-content/uploads/2016/05/dithering-1-... (best visible at th…

HN discussionI had to figure this out recently, a couple things that really helped me are Erin Catto's GDC lectures (particularly [1]) and Allen Chou's game physics articles [2]. I think of a Jacobian as a way to transform the velocities from however they're stored for the interacting objects into linear world-space velocities. For example, in 2D rigid body physics, rotational velocity is usually just a single number representin…
