[vtkusers] Color of texture map on isosurface

[Michael]

Hello,
As a VTK newbie I am experiencing troubles in assigning color to an isosurface 
using texture mapping.

The color of the isosurface automatically varies from red to blue as the value 
increases from the minimum value (0) to the maximum value (1). As the color 
of the isosurface changes, the color of the texture map also varies as it is 
influenced by the original color.

What can I do to exactly assign the texture map plus its color to the 
isosurface? I am using/hacking TCL, by the way.

Thanks in advance,
Michael ten Caat
