|
* @brief Axis aligned hyper tree grid cut
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* Cut an hyper tree grid along an axis aligned plane and output a hyper
|
||
|
|
* tree grid lower dimensionality. Only works for 3D grids as inputs
|
||
|
|
*
|
||
|
|
* NB: This new (2014-16) version of the class is not to be confused with
|
||
|
|
* earlier (2012-13) version that produced a vtkPolyData output composed of
|
||
|
|
* disjoint (no point sharing) quadrilaterals, with possibly superimposed
|
||
|
|
* faces when cut plane contained inter-cell boundaries.
