Problems with vtk3.1

[Lisa Sobierajski Avila]

Hello T. Ye,

I took the example polyTexture.tcl in graphics and added the following to it:

vtkImageViewer viewer
viewer SetInput structuredPoints
viewer SetColorWindow 1.0
viewer SetColorLevel 0.0
viewer SetZSlice 0
viewer Render

I was able to see the structured points in the image viewer without a 
problem. I am using a version of VTK more recent than the nightly. Are you 
using VTK 3.1 or a nightly?
