Author:

Curt A fast bounding sphere collision detector. Fast bounding spheres take less calculation and will hit all cases except that when an object is sort of parallel to the direction the sphere is moving. IE: It works with head on collisions where the direction vector goes straight into a triangle or boundingobject, but not if it runs alongside (but the boundingsphere still intersects to the left/right) This collision detector will use sourceObject's bounding sphere object to check for collisions against other triangles or bounding objects.
