[IDV #OXE-910941]: Fwd: What I was trying to do with IDV, apparently is easy to do...

Hi Dave-

At this point, no.  From the image, it looks to me like they
are regridding the data before doing the volume rendering.
(note the step like features in the back part of the image)  
We looked at regridding a while back, but it is was very 
compute intensive and we didn't pursue it further.  Note the
comments on the requirements for doing the volume rendering for
gr2analyst.  I tried gr2analyst on my machine and apparently
my graphics card is not compatible, so even if you are running
Windows, it may not be "easy to do".

It is something we can put on the wish list, though.   I tried
doing volume rendering of a level 2 file in the IDV, but it
turned out to be a better looking display of nested cones rather
than what the gr2analyst image showed.  To do that, load in
a Level II radar image, select the Any Field formula and a Volume Renderer
and when prompted for data, select the Reflectivity field.
