3D object of a brain?
Well, if you have any specifics about it you can get very accurate
results depending on the area in what you are looking at. What I
found to work better in regrads to looking at a hemisphere section of
the brain, is to use planar bump mapping as opposed to displace. I
say this because it is easier to get a more accurate representation
of the region that separates the parietal lobe from the temporal and
frontal lobes. But once again if you can be more specific I,
HOPEFULLY, can direct you to the most appropriate resources to
develop what you are looking for. Sam
