Hi, Has anyone used DX to visualize 3-D subsurface geologic units, a la EarthVision? I've discretized a pretty detailed geologic model and treated the array as connection-dependent so as to produce a volume of colored cells for visualization. However, this is very inefficient because the array can easily be too large for DX to handle on my machine (linux, Athlon, 1GB memory). And I can't reduce the resolution of the data set without losing important detail.
It seems that it would be much more efficient to convert each geologic unit (they are fairly continuous in space, i.e. mainly layers) to some sort of volume defined only by the geometry of its outer surfaces. This would eliminate all the interior data which are redundant anyway. Another alternative might be to simply use a "fence diagram"; that is, a series of cross sectional slices oriented in several directions, but a lot of information would be lost using this approach.
Any comments and/or suggestions would be appreciated. Thanks, Karl Pohlmann -- Karl Pohlmann Associate Research Hydrogeologist Division of Hydrologic Sciences Desert Research Institute 755 East Flamingo Road, Las Vegas, NV 89119 Phone: 702-862-5485 Fax: 702-862-5427
