I'm reading Bridson's paper <Robust Treatment of Collisions, Contact and Friction for Cloth Animation>. I have question about the collision response order.
Jacobi iterative approach (parallel rather than sequential) ...a Gauss-Seidel iterative approach
, (These are in chapter 4
Limiting the Strain and Strain Rate
), I don't quite understand this. In my view, for example, there are two collision pair which are interacted. A Jacobi approach will update the two pair using their old state in parallel. A Gauss-Seidel approach will upate first pair , then update the second pair with first pair's newest state. Am i correct? In Gauss-Seidel approach which pair should I update first? Thank you very much!!!
