Hi Miri,
you could also try to add a LookupTableProperty to your surface node you
want to have colored. That will allow you to specify the range of colors
your scalars will be visualized. That worked for my case also for the 2D
planes. What you have to do is:
- Create your specific lookup table mitk::LookupTable::Pointer lut
- Set the lookup table as a property to your node:
node->SetProperty("LookupTable",lut);
Regards,
Alex
