[IDV #JNS-730828]: volume rendering creates solid cube

Alexa,

This is the same data we were looking at before, correct? Were you able to 
clean up the data with respect to the longitude problem we saw before?

At any rate, I was able to visualize the data with no problems in the IDV just 
as you did. My only suggestion is you may wish to experiment with the 3D 
Surface -> Isosurface option instead of volume rendering. This will at least 
have the advantage of rendering much quicker than volume rendering -- your 
dataset is quite large. Also, it may clean up some of the visualization 
artifacts you are reporting.

Lastly, if you are going to the AMS meeting in Atlanta, stop by the Unidata 
booth for in-person IDV help.

Best,

Unidata IDV Support
