[vtkusers] Re: how to visualize a color volume

[Dr. Daniel James White PhD]

Hi,

we are also trying to do this,
we wanted to use the set independent components ON function in 
vtkRayCastMapper
but it is not longer in the code,
despite being in the documentation...!!!!

This looked like it would treat the RBG channels of a colour dataset 
individually as true colours,
and then you also need some alpha channel to use as the opacity 
function perhaps.

any Ideas Lisa A?
