6.18 NON-INTERACTIVE COLLISION DETECTION

As was already mentioned in the previous section, in interactive collision detection, collisions are detected between all objects. However, sometimes this is not necessary or even desirable especially when animating particle flocks consisting of thousands of particles. For example, when a man walks in snow, collisions between the man and individual snow particles should be detected and processed but snow particles need not collide with each other.

Non-interactive collision detection method is designed for these kind of applications. It processes collisions which occur between target objects and parameter objects of it. However, collisions between target objects or collisions between parameter objects are not processed.

So, let's practise this.
