3a84b05058 Added a new friction slope example (ground is rotating). Fixed a problem in the reduced deformable's friction (now clamp the maximum tangential impulse based on the tangential velocity impulse at the current iteration, not the total tangential velocity at the beginning) 2021-09-06 17:56:32 -04:00

52abe35e41 friction seems to be working. However, when the block is only sliding on the surface, there is no friction because no delta normal impulse...need to think 2021-08-25 00:38:29 -04:00
