[vtkusers] Two cut planes

[David.Pont at ForestResearch.co.nz]

Hi Chunyan,

   Clipping a object by a plane is available in my application. Now I want
   to
   clip this object by two planes. It is like cut one corner of the object.
   Could any one give me some help?

  There are a few possibilities:
  - Two instances of vtkPlane combined with vtkImplicitBoolean
  - vtkPlanes (seems to be 6 planes?)
  - two instances of vtlPlaneSource combined with vtkAppendPolyData, then
vtkImplicitModeller

 Happy clipping...
