Currently, I'm reading the Krishna Kumar's book "Learning Physics Modeling with PhysX".
Source code for the cloth example uses a method getRenderBuffer() to get points, triangles and quads that we define for the mesh description but he doesn't explain anything about this method on his book.
What does getRenderBuffer() actually do? Is this the (only) way to get updated cloth particles positions? If so, since getRenderBuffer() is a PxScene object's method, what should we do when we have lots of cloth actors in the scene?
