		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 Plane *	planes,
		udword	nb_planes,
		const Matrix4x4 *	worldm = `null`

protected

Initializes a collision query :

reset stats & contact status
compute planes in model space
check temporal coherence

Parameters

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

Returns: TRUE if we can return immediately

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

Definition at line 178 of file OPC_PlanesCollider.cpp.

◆ override()

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

◆ PlanesAABBOverlap()

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.

◆ PlanesTriOverlap()

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!
