* @brief convert 3D linear cells to vtkPolyhedra
|
||
|
|
*
|
||
|
|
* vtkConvertToPolyhedra is a filter that takes a vtkUnstructuredGrid as
|
||
|
|
* input and produces a vtkUnstructuredGrid on output, converting 3D linear
|
||
|
|
* cells such as tetrahedra, hexahedra, wedges, and pyramids into
|
||
|
|
* vtkPolyhedron.
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* Certain cells are skipped and not converted, this includes cells of dimension
|
||
|
|
* two or less (e.g., triangles, quads, lines, verts, and so on); and higher
|
||
|
|
* order cells that cannot easily be converted to vtkPolyhedra. (TODO: tessellate
|
||
|
|
* high-order 3D cell faces and then use these to form the polyhedra.)
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* This filter is typically used for testing. In general, processing linear cells
|
||
|
|
* is preferrable to processing polyhedra due to differences in speed of processing,
|
||
|
|
* and memory requirements.
