This is a simple question, I assume there is an easy way to get this info. What I'd like to do is fracture my rigid body if it collides with another rigid body with sufficient force. This question is not about fracturing, I have method for that, what I would like to know is how to query the strength of the impact between two rigid bodies. Is there a simple method call for this? or must I manually calculate it as a function of the velocities, mass, angle of impact, etc.?
Help is appreciated!
