Can't correctly volume rendering UGRID data from GeoFlow

[clyne]

The OSPray volume renderer does not render the UGRID data from GeoFlow correctly. The data set fills the entire domain, however an OSPRay volume rendering only draws something on one side of the domain as seen in the attached image.

To reproduce:

1. Import the all of the UGRID files in /glade/p/cisl/vast/vapor/data/Source/UGRID/NOAA-geoflow/small (note, need to use the UGRID, not CF importer)
2. Enable the volume renderer

@clyne have you confirmed that the grid is being imported correctly? I looked at the wireframe and, while I cannot be sure as I am unfamiliar with this data format, it does not look quite right to me. Also, I cannot see any discernible patterns in any of the variables over the noise.

The wireframe looks reasonably correct to me, though it is hard to tell with 3D and perspective projection. I've attached an image using orthographic projection. The data also looks correct (verified by the NOAA people). See the attached slice of 'dtotal' variable.

Ok, sounds good. It does look quite different from the other unstructured datasets I've worked with so far. I can see the variables clearly in your picture. I was looking at the wireframe and the data is too high frequency to see clearly in the wireframe alone, my bad.
