<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>i am using a <FONT size=2>vtkWarpScalar to create a
3D image. Unfortunately, some scalar are set to vtk_min_float so the z is very
low and when I try to render the image I see nothing.... Is it possible to
change the bounding box to see something. I have looked on the on line help but
I don't see a SetBounds method....</FONT></FONT></DIV>
