What is Collision Detection?

Collision detection is one of the largest subjects in advanced 3D programming. It is the process of determining whether two polygons are touching or intersecting and taking the most appropriate action to deal with this – usually this involves limiting character movement. Director provides some built-in tools to help out with this: namely the Collision Modifier.

By attaching the collision modifier to objects in a 3D world, we can detect collisions with between all the objects to which the modifier has been applied.
