Yeah I found the constraints now, for some reason I failed to notice those this afternoon. I cannot find where they are actually checked in the code though. I guess that is probably done inside the particle library. At the moment I still have not found a way to get a handle on the collision information without just simulating it externally, but that still seems like a less than optimal way to go about this.
