We would be very interested in the VisIT part of this.
We (California Dept Water Resources) have started testing a plugin for VisIT
for 2D layered meshes with triangles in projected coordinates and some mix
of S-Z coordinates. The specific effort originates from work with SELFE,
which has a mix of data centerings and also a time dimension. Our more
general interest extends to other meshes that are the cross-product of a
horizontal unstructured mesh and a structured vertical mesh.
We are willing to collaborate or build out our own work a certain distance
to accommodate other people's use cases. In particular, we would be
delighted to get our hands on a mesh with data from 1-2 other groups to make
sure our approach doesn't ignore opportunities and to get a sense how the
UGRID proposal is getting interpreted since I have noticed different
programmers take different liberties.
Whether or not this effort will provide efficient parallel visualization is
another matter. I wrote about some of the issues involved in an earlier
thread.
