Hi guys,

I am trying to implement a Multi Dimensional  transfer function design;
similar to the work done by Kindlmann and Kniss et Al.
I have not found anything useful in VTK to achieve this,  there was also a
similar question posted a few years ago but there was no response, i dont
know if now more people are aware of how this can be achieved.

In VTK, i have found colour and opacity mappings that take their domain
from *either* scalar values or gradient lookup tables, but not both
I would like to have greater control over the rendering process , find a way
to set colour and opacities to particular voxels of my choosing.

Can someone kindly tell me how this can be achieved, or at least guide me in
the correct direction.

Thanks in advance,

Tony Marrero
