[vtk-developers] How to use color mapping for vtkPistonMapper?

[David E DeMarle]

Unfortunately I ran out of time and didn't get around to moving VTK's
lookup table over when I originally implemented that class. So, the randow
color map you see now is the only option when doing direct GPU to GPU
rendering. Unless you hack the class yourself to make the transfer function
configurable of course.

If anyone out there has an updated implementation (ahem John B.) please
direct us to it and we can see about folding your improvements in.

thanks
