Thanks! that is similar to what I am currently trying to do, but also fits another application of GIS that I need to eventually get to.<br><br>that link is truly an incredible application of GIS. that is a very powerful illustration. It seems that I need to look into NVIZ. That may also explain the use of negative depth values, which i didnt understand in the raster data model.
