Detailed Description

Contains a sphere-vs-tree collider. This class performs a collision test between a sphere and an AABB tree. You can use this to do a standard player vs world collision, in a Nettle/Telemachos way. It doesn't suffer from all reported bugs in those two classic codes - the "new" one by Paul Nettle is a debuggued version I think. Collision response can be driven by reported collision data - it works extremely well for me. In sake of efficiency, all meshes (that is, all AABB trees) should of course also be kept in an extra hierarchical structure (octree, whatever).

Generic collision query for generic OPCODE models. After the call, access the results:

Parameters

cache	[in/out] a sphere cache
sphere	[in] collision sphere in local space
model	[in] Opcode model to collide with
worlds	[in] sphere's world matrix, or null
worldm	[in] model's world matrix, or null

Returns: true if success

Warning: SCALE NOT SUPPORTED. The matrices must contain rotation & translation parts only.
