[AWIPS #PKL-461542]: Missing features AWIPS Cave from Centos VM versus native Nvidia grajphics on Linux ?



Hi there,

This specific limitation can be seen if you try to load any satellite RGB 
products from
the menu (see attached screenshot).  With the ability to run directly on the 
graphics card
(as with the Windows and CentOS direct installs) you should be able to see 
products like
the ones shown in this blog about CIRA colorized GOES data:

The only limitation we're aware of is the display of RGB satellite images as 
mentioned above.

I think as long as your OS supports VMware Workstation Player 
(https://www.vmware.com/products/workstation-player.html) then you should 
always be able to run
the CAVE VM we build and distribute.

As far as we know, the limitation is pretty isolated, so I don't think we'll be 
producing a
video to demonstrate it.

Thank you, yes I believe we'll be aiming to put the next version of AWIPS out 
on Rocky8.
Thanks, and enjoy AMS next week!
