[vtkusers] vtkProjectedPolyDataRayBounder problem

[Lisa Avila]

Hi Jainlong,

The good news is you won't have this problem in VTK 4.0. The bad news is 
that is because vtkProjectedPolyDataRayBounder no longer exists.

The problem you are experiencing is due to clipping. If you set the 
clipping range of the camera yourself this should fix the problem (unless 
you are really close your camera position is within the clipping sphere).
