Cory and vtkusers,<br><br>Is there any way to use vtkcolortransferFunction with vtkActor or is it only applicable with vtkVolume?<br><br>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?<br>
<br>thanks,<br><br>John<br><br><div class="gmail_quote">On Tue, Sep 29, 2009 at 6:15 AM, Cory Quammen <span dir="ltr"><<a href="mailto:cquammen@cs.unc.edu">cquammen@cs.unc.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

I don't believe that this is possible with existing classes in VTK.<br>
You could try subclassing vtkLookupTable or vtkColorTransferFunction.<br>
