There is a need here to show "fault planes" and geological formation boundaries in 3D, inside the earth. They are irregularly curved surfaces, or in VisAD terms, a 2D manifold in 3D space. Can VisAD / IDV do this, and if so what NetCDF data format is used? The data available to use would be a collection of (lat,lon,altitude) triplets, irregularly spaced, not on a grid.Right now we don't handle anything like this. You could try to create a new Data source class that creates an Irregular3DSet, mapping (Lat,Lon,Alt) -> some fixed value. Then try showing this data as an Isosurface.
As a hack for you now you could also define your shape as point data and let the station model display show it with decluttering off using a spherical layout model, sort of like a plume display.
