Bendy Cubes: Reprojecting 3D Data
So we are beginning serious work on some products which will end up marrying the 3-D world of subsurface modeling and the 2.5- & 3-D world of GIS. While the terrain modeling and multi-patch stuff in ESRI products qualifies as truly 3D, (and handling that with elliptical math garners extra points), ESRI has no support for 3D gridded data, e.g. seismic volumes. GRASS does. GDAL does not. And we're dealing with reprojecting these voxels, not just regridding or visualizing. Any brilliant tips out there? Something tells me we're straying out of the world of mainstream GIS towards the world of scientific computing.

there are specialized software out there, in the seismic/geologic modelling realm that seem to thing they are GISes just because they use some coordinate system.
However, they are unable to accept projection info, much less reproject something.
AFAIK, the only way to reproject seismic data is to reprocess it. Long, tedious and costly process.
Certainly, the current state of things is far from optimal.
