The only issue with iterative constraint solvers is the 'long chain' problem, where it's not possible to solve for longer stiff chains of constraints. Direct solvers can do it, but not with reasonable performance/memory usage.
- erwincoumans 4y agoIndeed, you can add a Featherstone articulated body algorithm implementation for such cases, or direct solver with good performance (see Maciej Mizerkski talk on Roblox solver here: https://youtube.com/watch?v=P-WP1yMOkc4 https://youtube.com/watch?v=P-WP1yMOkc4)
- MrScruff 4y agoVery interesting, thanks for the link!
