MR_findCollidingTriangleBitsets()

MRC_API MR_std_pair_MR_FaceBitSet_MR_FaceBitSet * MR_findCollidingTriangleBitsets	(	const MR_MeshPart *	a,
		const MR_MeshPart *	b,
		const MR_AffineXf3f *	rigidB2A )

the same as findCollidingTriangles, but returns one bite set per mesh with colliding triangles Generated from function MR::findCollidingTriangleBitsets. Parameter a can not be null. It is a single object. Parameter b can not be null. It is a single object. Parameter rigidB2A defaults to a null pointer in C++. Never returns null. Returns an instance allocated on the heap! Must call MR_std_pair_MR_FaceBitSet_MR_FaceBitSet_Destroy() to free it when you're done using it.

MR_findCollidingTriangles()

MRC_API MR_std_vector_MR_FaceFace * MR_findCollidingTriangles	(	const MR_MeshPart *	a,
		const MR_MeshPart *	b,
		const MR_AffineXf3f *	rigidB2A,
		const bool *	firstIntersectionOnly )

finds all pairs of colliding triangles from two meshes or two mesh regions

Parameters

rigidB2A

rigid transformation from B-mesh space to A mesh space, nullptr considered as identity transformation

firstIntersectionOnly

if true then the function returns at most one pair of intersecting triangles and returns faster Generated from function MR::findCollidingTriangles. Parameter a can not be null. It is a single object. Parameter b can not be null. It is a single object. Parameter rigidB2A defaults to a null pointer in C++. Parameter firstIntersectionOnly has a default argument: false, pass a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_std_vector_MR_FaceFace_Destroy() to free it when you're done using it.

MR_findSelfCollidingTriangles_4()

MRC_API MR_expected_std_vector_MR_FaceFace_std_string * MR_findSelfCollidingTriangles_4	(	const MR_MeshPart *	mp,
		MR_PassBy	cb_pass_by,
		MR_std_function_bool_from_float *	cb,
		const MR_Face2RegionMap *	regionMap,
		const bool *	touchIsIntersection )

finds all pairs of colliding triangles from one mesh or a region Generated from function MR::findSelfCollidingTriangles. Parameter mp can not be null. It is a single object. Parameter cb has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Parameter regionMap defaults to a null pointer in C++. Parameter touchIsIntersection has a default argument: false, pass a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_std_vector_MR_FaceFace_std_string_Destroy() to free it when you're done using it.

MR_findSelfCollidingTriangles_5()

MRC_API MR_expected_bool_std_string * MR_findSelfCollidingTriangles_5	(	const MR_MeshPart *	mp,

		const MR_Face2RegionMap *	regionMap,
		const bool *	touchIsIntersection )

finds all pairs (or the fact of any self-collision) of colliding triangles from one mesh or a region Generated from function MR::findSelfCollidingTriangles. Parameter mp can not be null. It is a single object. Parameter cb has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Parameter regionMap defaults to a null pointer in C++. Parameter touchIsIntersection has a default argument: false, pass a null pointer to use it. Never returns null. Returns an instance allocated on the heap! Must call MR_expected_bool_std_string_Destroy() to free it when you're done using it.

MR_findSelfCollidingTrianglesBS()

MRC_API MR_expected_MR_FaceBitSet_std_string * MR_findSelfCollidingTrianglesBS	(	const MR_MeshPart *	mp,

the same findSelfCollidingTriangles but returns the union of all self-intersecting faces Generated from function MR::findSelfCollidingTrianglesBS. Parameter mp can not be null. It is a single object. Parameter cb has a default argument: {}, pass MR_PassBy_DefaultArgument and a null pointer to use it. Parameter regionMap defaults to a null pointer in C++. Parameter touchIsIntersection has a default argument: false, pass a null pointer to use it. Never returns null. Returns an instance allocated on the heap!
