|
* @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.
