Hi David, I used to work in the oil-gas sector so I'm rather familiar with needs for visualizing large seismic horizon meshes, albeit a bit rusty - it was last century that I did the work :-)
VPB and osgEarth aren't likely to be too helpful for you as they really aren't geared up for the quite specific type of needs you have. What route you take depends upon some of the constraints that you might be able to put upon the geometry. For instance, is it a regular grid with holes, or does this mesh need to be an irregular triangle mesh? Robert.
