[vtkusers] vtkOBBTree functionality without rendered representation

[Surajit Nundy]

Hi,
	I have been successfully using vtkOBBTree for sometime now in Java+VTK 
using code adapted from OBBCylinder.tcl (partly copied below).  I would 
now like to use its functionality without it being rendered.  When I
1) do not use the last line (SetRepresentationToPoints) a visual 
surface analog appears, or change it to
2) SetRepresentation 0, I still see rendered points.

Is there some way that I can use vtkOBBTree's functionality 
(InsideOrOutside) without rendering it?

Thanks
