8.8. Collision Detection
This function defines you as a collision volume - a 3D object that can navigate around and interact with
the model, obeying certain physical rules that confine you within the model itself. In other words, you have
a mass and as such, cannot pass through other objects, points or lines in the scene.
You can walk over, or climb over objects in the scene that are up to half the height of the collision volume,
thus allowing you to walk up stairs, for example.
The collision volume, in its basic form, is a sphere (with radius = r), that can be extruded to give it height
(with height = h >= r). See diagram below:
