[vtkusers] LUT

[Csaba Palotai]

Hi List,

I have a volume with different species in it and would like to color it 
based on which gridbox has which species.
For this I use an array and the value for an element is 1 if it's water, 
2 if ammonia, 3 if both, 4 if none. (additional species will be added 
later)
I'd like to color my graph based on these values, which happens fine 
with the original LUT.
When I create my own because I need some certain colors (white for 
water, tan for ammonia, etc.)
So I use
lut->SetNumberOfColors(4);
lut->Build();
but then when I try to assign colors for the values it just doesn't work.
( I assign this LUt later to the mapper so the problem is something else)

Anybody with any ideas/suggestions/experience?
Any help is appreciated

Regards,
Csaba
