utility functions for use with PxTetrahedronMesh and subclasses

Member Function Documentation

void physx::PxTetrahedronMeshExt::extractTetMeshSurface	(	const PxTetrahedronMesh *	mesh,
		PxArray< PxU32 > &	surfaceTriangles,
		PxArray< PxU32 > *	surfaceTriangleToTet = `NULL`,
		bool	flipTriangleOrientation = `false`
	)

static

Extracts the surface triangles of a tetmesh

The extracted triangle's vertex indices point to the vertex buffer of the tetmesh.

Parameters

[in]	mesh	The mesh from which the surface shall be computed
[in]	surfaceTriangles	The resulting surface triangles
[in]	surfaceTriangleToTet	Optional array to get the index of a tetrahedron that is adjacent to the surface triangle with the corresponding index
[in]	flipTriangleOrientation	Reverses the orientation of the ouput triangles

void physx::PxTetrahedronMeshExt::extractTetMeshSurface	(	const void *	tetrahedra,
		PxU32	numTetrahedra,
		bool	sixteenBitIndices,
		PxArray< PxU32 > &	surfaceTriangles,
		PxArray< PxU32 > *	surfaceTriangleToTet = `NULL`,
		bool	flipTriangleOrientation = `false`
	)

static

Extracts the surface triangles of a tetmesh

The extracted triangle's vertex indices point to the vertex buffer of the tetmesh.

Parameters

[in]	tetrahedra	The tetrahedra indices
[in]	numTetrahedra	The number of tetrahedra
[in]	sixteenBitIndices	If set to true, the tetrahedra indices are read as 16bit integers, otherwise 32bit integers are used
[in]	surfaceTriangles	The resulting surface triangles
[in]	surfaceTriangleToTet	Optional array to get the index of a tetrahedron that is adjacent to the surface triangle with the corresponding index
[in]	flipTriangleOrientation	Reverses the orientation of the ouput triangles

PxI32 physx::PxTetrahedronMeshExt::findTetrahedronClosestToPoint	(	const PxTetrahedronMesh *	mesh,
		const PxVec3 &	point,
		PxVec4 &	bary
	)

static

Returns the index of the tetrahedron closest to a point

Parameters

[in]	mesh	The tetmesh
[in]	point	The point to find the closest tetrahedron for
[in]	bary	The barycentric coordinates of the point in the tetrahedron

PxI32 physx::PxTetrahedronMeshExt::findTetrahedronContainingPoint	(	const PxTetrahedronMesh *	mesh,
		const PxVec3 &	point,
		PxVec4 &	bary,
		PxReal	tolerance = `1e-6f`
	)

static

Returns the index of the tetrahedron that contains a point

Parameters

[in]	mesh	The tetmesh
[in]	point	The point to find the enclosing tetrahedron for
[in]	bary	The barycentric coordinates of the point inside the enclosing tetrahedron
[in]	tolerance	Tolerance value used classify points as inside if they lie exactly a tetrahedron's surface

Returns: The index of the tetrahedon containing the point, -1 if not tetrahedron contains the opoint
