<BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Howdy.<BR><BR>Here comes a question from someone who quite recently started using VTK <BR>4.2 on Windows XP. So far I've used VTK to visualize a tessellated <BR>surface of the brain reconstructed from MR images.<BR><BR>I then want to move on to color the surface in grey tones according to <BR>voxel intensities of the surface points. I first tried to use vtkTexture <BR>to load a (3D) vtkImageData filled with voxel intensities from the MR <BR>image volume. However, since vtkTexture only supports 2D texture maps I <BR>had to give up this effort.<BR><BR>Then I've tried to assign texture coordinates to the points that define <BR>the tessellated surface, but I see no effect on the surface rendered. <BR>Does anyone have some example for me to look at? I don't find relevant <BR>suggestions in the examples shipped with VTK.<BR><BR>Kind regards<BR>Jens Ivar
