Hello guys, I am not sure if this is the correct forum for this, but here goes: My problem is as follows. I have a surface triangular mesh. Each of the vertices of the mesh has a velocity associated with it. The vertices are moved for a unit time. So this movement is always not possible as there could be self-collisions of the mesh (Please think in terms of cloth simulation). Since my problem is not cloth simulation, My collision response should be different. My final aim of this vertex motion is to get the new shape of the mesh at time t = 1. I should have a valid surface mesh, that accounts for the self collsions. a) I am not exactly sure what my collision reponse should be. After a collision, say triangle vertex type of collision, How should these entities move? Right now I am just stopping their motion, but I don't think that's "right". b) After the motion, I have a bunch of mesh entities in the "interface" where two different surfaces collided. This part of the mesh is not redundant. Any idea on how to remove that? Thanks!
