* @class vtkHyperTreeGridToUnstructuredGrid
|
|
* @brief Convert hyper tree grid to
|
|
* unstructured grid.
|
|
*
|
|
*
|
|
* Make explicit all leaves of a hyper tree grid by converting them to cells
|
|
* of an unstructured grid.
|
|
* Produces segments in 1D, rectangles in 2D, right hexahedra in 3D.
|
|
* NB: The output will contain superimposed inter-element boundaries and pending
|
|
* nodes as a result of T-junctions.
