    • destroy

      public void destroy()

    • getMaterialIndices

      public PxTypedStridedData_PxU16 getMaterialIndices()
      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

    • setMaterialIndices

      public void setMaterialIndices(PxTypedStridedData_PxU16 value)
      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);

      Default: NULL

    • getPoints

      public PxBoundedData getPoints()
      Pointer to first vertex point.

    • setPoints

      public void setPoints(PxBoundedData value)
      Pointer to first vertex point.

    • getTetrahedrons

      public PxBoundedData getTetrahedrons()
      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.

    • setTetrahedrons

      public void setTetrahedrons(PxBoundedData value)
      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.

    • getFlags

    • getTetsPerElement

      public short getTetsPerElement()
      Used for simulation meshes only. Defines if this tet mesh should be simulated as a tet mesh, or if a set of tetrahedra should be used to represent another shape, e.g. a hexahedral mesh constructed from 5 or 6 elements.

    • setTetsPerElement

      public void setTetsPerElement(short value)
      Used for simulation meshes only. Defines if this tet mesh should be simulated as a tet mesh, or if a set of tetrahedra should be used to represent another shape, e.g. a hexahedral mesh constructed from 5 or 6 elements.
