// .NAME vtkBoxClipDataSet - clip an unstructured grid
//
// .SECTION Description
// Clipping means that is actually 'cuts' through the cells of the dataset,
// returning tetrahedral cells inside of the box.
// The output of this filter is an unstructured grid.
//
// This filter can be configured to compute a second output. The
// second output is the part of the cell that is clipped away. Set the
// GenerateClippedData boolean on if you wish to access this output data.
//
// The vtkBoxClipDataSet will triangulate all types of 3D cells (i.e, create tetrahedra).
// This is necessary to preserve compatibility across face neighbors.
//
// To use this filter,you can decide if you will be clipping with a box or a hexahedral box.
// 1) Set orientation
// if(SetOrientation(0)): box (parallel with coordinate axis)
// SetBoxClip(xmin,xmax,ymin,ymax,zmin,zmax)
// if(SetOrientation(1)): hexahedral box (Default)
// SetBoxClip(n[0],o[0],n[1],o[1],n[2],o[2],n[3],o[3],n[4],o[4],n[5],o[5])
// PlaneNormal[] normal of each plane
// PlanePoint[] point on the plane
// 2) Apply the GenerateClipScalarsOn()
// 3) Execute clipping Update();
