[vtkusers] Resolved: vtkLookupTable and three colors.

[Leguay Romain]

Hello everyone!
In my previous message, I tried to build a lookup table containing 3  
colors. I resolved this problem like this:
lookupTable.SetNumberOfColors(nbColors);
lookupTable.SetHueRange(240. / 360., 0);
lookupTable.SetSaturationRange(-1., 1.);

Regards,
Romain
