The topics covered in this chapter are as follows:
This chapter covers collision detection and some other important topics related to it. A collision can only occur when two or more bodies having definite shape collide with (hit) each other. Therefore, for a PhysX rigid body actor, a shape is always required to define its spatial volume.
We have already learnt about shapes and materials in Chapter 2, Basic Concepts, where we saw that creating a shape in PhysX requires an object of
