Roblox Solved The Physics Problem That Stumped Everyone!

Roblox and University of Utah developed Augmented Vertex Block Descent (AVBD), a physics simulation method that solves complex collision and constraint problems that stumped previous techniques. The method can simulate millions of particles at 100 FPS on consumer graphics cards and correctly handles challenging scenarios like heavy objects on light chains, chain mail collisions, and spring-connected blocks where older methods failed completely.
