Member Enumeration Documentation

◆ PxMeshFormat

enum physx::PxTetrahedronMeshDesc::PxMeshFormat

Defines the tetrahedron structure of a mesh.

Enumerator
eTET_MESH	Normal tetmesh with arbitrary tetrahedra.
eHEX_MESH	6 tetrahedra in a row will form a hexahedron

Member Data Documentation

◆ materialIndices

PxTypedStridedData<PxFEMMaterialTableIndex> physx::PxTetrahedronMeshDesc::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: PxFEMMaterialTableIndex index = *(PxFEMMaterialTableIndex *)(((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

◆ tetrahedrons

PxBoundedData physx::PxTetrahedronMeshDesc::tetrahedrons

Pointer to first tetrahedron.

Caller may add tetrhedronStrideBytes bytes to the pointer to access the next tetrahedron.

These are quadruplets of 0 based indices: vert0 vert1 vert2 vert3 vert0 vert1 vert2 vert3 vert0 vert1 vert2 vert3 ...

where vertex is either a 32 or 16 bit unsigned integer. There are numTetrahedrons*4 indices.

This is declared as a void pointer because it is actually either an PxU16 or a PxU32 pointer.
