vtkBoxClipDataSet

Section: Visualization Toolkit Graphics Classes

Usage

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();

To create an instance of class vtkBoxClipDataSet, simply invoke its constructor as follows

  obj = vtkBoxClipDataSet
