|
||
|
|
* @brief clip an unstructured grid
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* 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();
