Public Types

enum PxMeshFormat

Defines the tetrahedron structure of a mesh.

Values:

enumerator eTET_MESH: Normal tetmesh with arbitrary tetrahedra.

enumerator eHEX_MESH: 5 or 6 tetrahedra in a row will form a hexahedron

Public Functions

inline PxTetrahedronMeshDesc(): Constructor to build an empty tetmesh description.

inline PxTetrahedronMeshDesc(physx::PxArray<physx::PxVec3> &meshVertices, physx::PxArray<physx::PxU32> &meshTetIndices, const PxTetrahedronMeshDesc::PxMeshFormat meshFormat = eTET_MESH, PxU16 numberOfTetsPerHexElement = 5): Constructor to build a tetmeshdescription that links to the vertices and indices provided.

inline bool isValid() const

Public Members

PxTypedStridedData<PxDeformableMaterialTableIndex> materialIndices

Optional pointer to first material index, or NULL.

There are PxTetrahedronMesh::numTriangles indices in total. Caller may add materialIndexStride bytes to the pointer to access the next triangle.

When a tetrahedron mesh collides with another object, a material is required at the collision point. If materialIndices is NULL, then the material of the PxShape instance is used. Otherwise, if the point of contact is on a tetrahedron with index i, then the material index is determined as: PxDeformableMaterialTableIndex index = *(PxDeformableMaterialTableIndex *)(((PxU8*)materialIndices) + materialIndexStride * i);

If the contact point falls on a vertex or an edge, a tetrahedron adjacent to the vertex or edge is selected, and its index used to look up a material. The selection is arbitrary but consistent over time.

Default: NULL
