[vtkusers] BandContourTerrain.tcl demo

[Nigel Nunn]

Testing a current CVS version (Win2K, VC6).  This demo 
 
  Examples/VisualizationAlgorithms/Tcl/BandContourTerrain.tcl
 
does not seem to render the image.  If I comment out the 
following few lines, it renders the scene correctly: 

#  vtkCamera cam
#    cam SetPosition -17438.8 2410.62 25470.8
#    cam SetFocalPoint 3985.35 11930.6 5922.14
#    cam SetViewUp 0 0 1
#  ren1 SetActiveCamera cam
#  ren1 ResetCameraClippingRange

Also noticed that simply calling Zoom works fine:

  [ren1 GetActiveCamera] Zoom 2

But calling any of these destroys the display:

  SetPosition, 
  SetFocalPoint, 
  SetViewUp 
 
Any ideas what might be causing this? 
thanks, 
Nigel
