<DIV><FONT face=Arial size=2>thank you for your mail. But my question is
*how* do I assign colors to my vertices? I have a contour derived from a
voxel set, i.e. purely geometrical data, and a separate voxel set providing
temperatures. I don't know how to assign the temperature to the
vertices.</FONT></DIV>

<DIV><FONT face=Arial size=2>Dear vtk-experts,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have derived contours from an anatomical
voxel set (similar to the examples Medical1,2,3 that come with
vtk).</FONT></DIV>
<DIV><FONT face=Arial size=2>Now I would like to color this surface
according to some spatially varying function, e.g. local body temperature
that I have given as a second voxel array.</FONT></DIV>
<DIV><FONT face=Arial size=2>I suppose I have to tell the vtkPolyMapper to
take the colors from my array, but how?</FONT></DIV>
