Detailed Description

A tetramedron mesh, also called a 'tetrahedron soup'.

It is represented as an indexed tetrahedron list. There are no restrictions on the tetrahedron data.

To avoid duplicating data when you have several instances of a particular mesh positioned differently, you do not use this class to represent a mesh object directly. Instead, you create an instance of this mesh via the PxTetrahedronMeshGeometry and PxShape classes.

Creation

To create an instance of this class call PxPhysics::createTetrahedronMesh(), and release() to delete it. This is only possible once you have released all of its PxShape instances.

Member Function Documentation

◆ getLocalBounds()

virtual PxBounds3 physx::PxTetrahedronMesh::getLocalBounds ( ) const

pure virtual

Returns the local-space (vertex space) AABB from the tetrahedron mesh.

Returns: local-space bounds

Implemented in physx::Gu::TetrahedronMesh.

◆ getNbTetrahedrons()

virtual PxU32 physx::PxTetrahedronMesh::getNbTetrahedrons ( ) const

pure virtual

Returns the number of tetrahedrons.

Returns: number of tetrahedrons

See also: getTetrahedrons()

Implemented in physx::Gu::TetrahedronMesh.

◆ getNbVertices()

virtual PxU32 physx::PxTetrahedronMesh::getNbVertices ( ) const

pure virtual

Returns the number of vertices.

Returns: number of vertices

See also: getVertices()

Implemented in physx::Gu::TetrahedronMesh.

◆ getTetrahedraRemap()

virtual const PxU32 * physx::PxTetrahedronMesh::getTetrahedraRemap ( ) const

pure virtual

Returns the tetrahedra remapping table.

The tetrahedra are internally sorted according to various criteria. Hence the internal tetrahedron order does not always match the original (user-defined) order. The remapping table helps finding the old indices knowing the new ones:

remapTable[ internalTetrahedronIndex ] = originalTetrahedronIndex

Returns: the remapping table (or NULL if 'PxCookingParams::suppressTriangleMeshRemapTable' has been used)

See also: getNbTetrahedron() getTetrahedrons() PxCookingParams::suppressTriangleMeshRemapTable

Implemented in physx::Gu::TetrahedronMesh, and physx::Gu::BVTetrahedronMesh.

◆ getTetrahedronMeshFlags()

virtual PxTetrahedronMeshFlags physx::PxTetrahedronMesh::getTetrahedronMeshFlags ( ) const

pure virtual

Reads the PxTetrahedronMesh flags.

See the list of flags PxTetrahedronMeshFlags

Returns: The values of the PxTetrahedronMesh flags.

Implemented in physx::Gu::TetrahedronMesh.

◆ getTetrahedrons()

virtual const void * physx::PxTetrahedronMesh::getTetrahedrons ( ) const

pure virtual

Returns the tetrahedron indices.

The indices can be 16 or 32bit depending on the number of tetrahedrons in the mesh. Call getTetrahedronMeshFlags() to know if the indices are 16 or 32 bits.

The number of indices is the number of tetrahedrons * 4.
