[vtkusers] Visualising 3D RGB data

[Steven Kenny]

I have a set of data that consists of RGB values at a set of uniform  
points. I can create either a vtkStructuredGrid or a vtkImageData  
object out of this. What I then want to do is to take slices through  
this and visualise these. I have tried playing vtkCutter and vtkPlane  
to take slices through the data and visualise these. It seems to me  
that I can only visualise vector data either by magnitude or by the  
value of one of the components using this technique. Can anyone  
suggest a technique that will allow me to view the RGB data on a  
slice through the object instead.

Thanks,

Steven
