* @class vtkLinearCellExtrusionFilter
* @brief extrude polygonal data to create 3D cells from 2D cells
*
* vtkLinearCellExtrusionFilter is a modeling filter. It takes polygonal data as
* input and generates an unstructured grid data on output. The input dataset is swept
* according to the input cell data array value along the cell normal and creates
* new 3D primitives.
* Triangles will become Wedges, Quads will become Hexahedrons,
* and Polygons will become Polyhedrons.
* This filter currently takes into account only polys and discard vertices, lines and strips.
* Unlike the vtkLinearExtrusionFilter, this filter is designed to extrude each cell independently
* using its normal and its scalar value.
