Re: Curved 2D surfaces in 3D

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.

Hi Stu:

there is an effort in CF to define a format for unstructured grids in netcdf. See:

 http://cf-pcmdi.llnl.gov/trac/ticket/6

this efffort is still in process, but we will (eventually) read the format that is defined into the common data model.
