[vtkusers] Using vtkLookupTable

[John Durkin]

Cory and vtkusers,

Is there any way to use vtkcolortransferFunction with vtkActor or is it only
applicable with vtkVolume?

Also any pointers on how to go about having one scalar map the hue and
another scalar map to the value (HSV) of the vtkPolyData?

thanks,

John
