public class E3DCollisionDetectorFastBoundingSphere

extends E3DCollisionDetectorSegment

implements E3DCollisionDetector

Author:

Curt 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 collisions that 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)
