[vtkusers] Problems With Gouraud shading.

[Steve Dorning]

I am having problems with Gouraud Shading. Setting the interpolation
method to Gouraud does not do anything.
 
I have tried this first in C++ then reproduces the problem in tcl.
 
Below is my  tcl code. I would appreciate any help with this matter.
 
Many Thanks in Advance,
 
Steven Dorning
