/**
* @class vtkDensifyPolyData
* @brief Densify the input by adding points at the
* centroid
*
*
* The filter takes any polygonal data as input and will tessellate cells that
* are planar polygons present by fanning out triangles from its centroid.
* Other cells are simply passed through to the output. PointData, if present,
* is interpolated via linear interpolation. CellData for any tessellated cell
* is simply copied over from its parent cell. Planar polygons are assumed to
* be convex. Funny things will happen if they are not.
*
* The number of subdivisions can be controlled by the parameter
* NumberOfSubdivisions.
