[vtkusers] Assigning colors in vtkPolyDataMapper

[Christian Zemlin]

Galina,

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.

  Try using yellow-green-blue gamma and see how it  looks.

    Dear vtk-experts,

    I have derived contours from an anatomical voxel set (similar to the examples Medical1,2,3 that come with vtk).
    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.
    I suppose I have to tell the vtkPolyMapper to take the colors from my array, but how?
