Inheritance diagram for vtkRectilinearGridToTetrahedra:
vtkRectilinearGridToTetrahedra forms a mesh of Tetrahedra from a vtkRectilinearGrid. The tetrahedra can be 5 per cell, 6 per cell, or a mixture of 5 or 12 per cell. The resulting mesh is consistent, meaning that there are no edge crossings and that each tetrahedron face is shared by two tetrahedra, except those tetrahedra on the boundary. All tetrahedra are right handed.
Note that 12 tetrahedra per cell means adding a point in the center of the cell.
In order to subdivide some cells into 5 and some cells into 12 tetrahedra: SetTetraPerCellTo5And12(); Set the Scalars of the Input RectilinearGrid to be 5 or 12 depending on what you want per cell of the RectilinearGrid.
If you set RememberVoxelId, the scalars of the tetrahedron will be set to the Id of the Cell in the RectilinearGrid from which the tetrahedron came.

This function for convenience for creating a Rectilinear Grid If Spacing does not fit evenly into extent, the last cell will have a different width (or height or depth). If Extent[i]/Spacing[i] is within tol of an integer, then assume the programmer meant an integer for direction i. |

This is called by the superclass. This is the method you should override. Reimplemented from vtkUnstructuredGridAlgorithm. |

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle. Reimplemented from vtkUnstructuredGridAlgorithm. |
