bool SphereCollider::Collide	(	SphereCache &	cache,
		const Sphere &	sphere,
		const Model &	model,
		const Matrix4x4 *	worlds = null,
		const Matrix4x4 *	worldm = null
	)

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

• with GetContactStatus()
• with GetNbTouchedPrimitives()
• with GetTouchedPrimitives()

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.

Definition at line 94 of file OPC_SphereCollider.cpp.

bool SphereCollider::Collide	(	SphereCache &	cache,
		const Sphere &	sphere,
		const AABBTree *	tree
	)

Collision query for vanilla AABB trees.

Parameters:

cache	[in/out] a sphere cache
sphere	[in] collision sphere in world space
tree	[in] AABB tree

Returns:

true if success

Definition at line 284 of file OPC_SphereCollider.cpp.

BOOL SphereCollider::InitQuery	(	SphereCache &	cache,
		const Sphere &	sphere,
		const Matrix4x4 *	worlds = null,
		const Matrix4x4 *	worldm = null
	)		[protected]

Initializes a collision query :

• reset stats & contact status
• setup matrices
• check temporal coherence

Parameters:

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

Returns:

TRUE if we can return immediately

Warning:

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

Definition at line 166 of file OPC_SphereCollider.cpp.

inline_ BOOL Opcode::SphereCollider::SphereAABBOverlap	(	const Point &	center,
		const Point &	extents
	)		[protected]

inline_ BOOL SphereCollider::SphereContainsBox	(	const Point &	bc,
		const Point &	be
	)		[protected]

Checks the sphere completely contains the box. In which case we can end the query sooner.

Parameters:

bc	[in] box center
be	[in] box extents

Returns:

true if the sphere contains the whole box

Definition at line 311 of file OPC_SphereCollider.cpp.

BOOL Opcode::SphereCollider::SphereTriOverlap	(	const Point &	vert0,
		const Point &	vert1,
		const Point &	vert2
	)		[protected]
