Hi,
I am using an unstructured global simulation model in which grid
elements are triangles instead of rectangular grid-boxes. Previous
messages on this list indicated that IDV can handle grids in which the
latitude and longitude can be functions of a 2-dimensional i-j index,
but my data might be too unstructured for this. I would also like to
use IDV to visualize data from a finite-volume atmospheric model in
which the rectangular grid sizes vary continuously from one grid box to
another. This finite-volume grid might also be too "unstructured" to
put onto a 2-d horizontal grid. In this model, the latitude and
longitude are a function of a single "i" dimension in the horizontal,
but I don't know if IDV can handle this.
I'm attempting to put the output from these models into netCDF
CF-convention format, but before I do I'm wondering what would be the
best way to get unstructured model results into IDV. I believe that
VisAD can handle visualizing unstructured grid, but I'm not sure what's
the best way to get IDV to understand my data.
Thanks for any help,
