Here comes a question from someone who quite recently started using VTK
4.2 on Windows XP. So far I've used VTK to visualize a tessellated
surface of the brain reconstructed from MR images.
I then want to move on to color the surface in grey tones according to
voxel intensities of the surface points. I first tried to use vtkTexture
to load a (3D) vtkImageData filled with voxel intensities from the MR
image volume. However, since vtkTexture only supports 2D texture maps I
had to give up this effort.
Then I've tried to assign texture coordinates to the points that define
the tessellated surface, but I see no effect on the surface rendered.
Does anyone have some example for me to look at? I don't find relevant
suggestions in the examples shipped with VTK.
