		const Model &	model,
		const Matrix4x4 *	worldm = `null`
	)

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

Parameters:

cache	[in/out] a planes cache
planes	[in] list of planes in world space
nb_planes	[in] number of planes
model	[in] Opcode model to collide with
worldm	[in] model's world matrix, or null

Returns:: true if success

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

		const OBB &	box,
		const Model &	model,
		const Matrix4x4 *	worldb = `null`,
		const Matrix4x4 *	worldm = `null`
	)		`[inline]`

BOOL PlanesCollider::InitQuery	(	PlanesCache &	cache,
		const Plane *	planes,
		udword	nb_planes,
		const Matrix4x4 *	worldm = `null`
	)		`[protected]`

PlanesCollider::override ( Collider ) const

Validates current settings. You should call this method after all the settings and callbacks have been defined for a collider.

Returns:: null if everything is ok, else a string describing the problem

Reimplemented from VolumeCollider.

inline_ BOOL PlanesCollider::PlanesAABBOverlap	(	const Point &	center,
		const Point &	extents,
		udword &	out_clip_mask,
		udword	in_clip_mask
	)		`[protected]`

Planes-AABB overlap test.

original code by Ville Miettinen, from Umbra/dPVS (released on the GD-Algorithms mailing list)
almost used "as-is", I even left the comments (hence the frustum-related notes)

Parameters:

center	[in] box center
extents	[in] box extents
out_clip_mask	[out] bitmask for active planes
in_clip_mask	[in] bitmask for active planes

Returns:: TRUE if boxes overlap planes

Definition at line 14 of file OPC_PlanesAABBOverlap.h.

inline_ BOOL PlanesCollider::PlanesTriOverlap ( udword in_clip_mask ) [protected]

Planes-triangle overlap test.

Parameters:

in_clip_mask [in] bitmask for active planes

Returns:: TRUE if triangle overlap planes

Warning:: THIS IS A CONSERVATIVE TEST !! Some triangles will be returned as intersecting, while they're not!
