Problem Sloving
RBD Intersection
There are intersections between my chairs if we look close. To solve this problem, I tried several things in Bullet Data. We can see geometry colliding in the solver if we show Guide Geometry. I use Convex Hull first, which is the default, and it’s not wrapping high-resolution shapes(without a dip or depression anywhere)(1). We can change it to other things, a box, for example, and my chair will move along with it because the transform is being applied to that. Most simple shapes solve very fast since they are just a few points. However, to get fewer intersections in my scene, I tried Concave(2). It fits my chair and works fine for one piece, but once you have a complex scene, it will be extremely slow and may not even work. My result here(3) is set up with Convex Hull, which is still pretty fast, solves most things correctly, and looks good here.
