Chapter 19. 3-D Collision Detection

Overview

Contrasting 2-D to 3-D, while there is nothing fundamentally different about the techniques of collision detection in 3-D, adding another dimension does make things more complicated. For one thing, the range of shapes in 3-D is much more complex. This is especially so with respect to the cylinder and the cone. Also, there are more ways for two objects not to collide. For example, while two non-parallel straight paths in 2-D will always intersect, in 3-D they will usually miss each other.

Even if complexities do arise, it remains that most of the techniques ...
