Detailed Description

create a Tetrahedral mesh from a RectilinearGrid

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.

Reimplemented from vtkUnstructuredGridSource.

int vtkRectilinearGridToTetrahedra::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkUnstructuredGridSource.

virtual int vtkRectilinearGridToTetrahedra::IsA ( const char * type ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

void vtkRectilinearGridToTetrahedra::PrintSelf ( ostream & os,

vtkIndent indent

) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkUnstructuredGridSource.

void vtkRectilinearGridToTetrahedra::SetInput ( const double Extent[3],

const double Spacing[3],

const double tol = 0.001

)

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.
