This is exactly what I have in mind.


To achieve this, you could create a color

Ok. I can easily setup such a LUT. I know as well how to assign it as a 
property to the rendering node. What would be interesting to me is, how 
to tell the mapper, which would be the "mitk::PointSetVtkMapper3D" in my 
case, that it should use point IDs as indices to the LUT.

Cheers,
Steffen
