Hi, I am really loving using Vapor, but whenever I attempt to use Volume or Isosurface, as soon as I click the square to check the box to display the variable, my linux machine locks up. I am using CENTOS 8. Is there a chance I could have more success by installing virtual workstation on my CENTOS 8 machine and loading CENTOS 7 on that? Was Vapor designed for CENTOS 7? Could this be why I am not able to use Isosurfaces
Hey Nathan, sorry about the freezing behavior. We just released VAPOR 3.5, so I wonder if you have given that a try? We would be much more happy to look at bugs in VAPOR 3.5.
Thanks very much Sam, it is really odd, I just loaded 3.5 and the same behavior freezing when initiating a Volume or Isosurface occurs. Is there anything unique to those prodcuts that would require different computer resources than the other renderers? I get very good response with all other renderers. I am using CENTOS8, and I know I have heard there are a lot of bugs that have been noted from 7 to 8 with many people preferring CENTOS7 instead of 8. Let me know if i can provide you any information on my particular computer. Thanks very much!
Can you provide information about your graphics card. Try running glxinfo and posting the output.

hi there, you can go ahead and close my thread down if thats possible. Tonight I was able to load Ubuntu 20.4 on a VMware virtual workstation. Isosurface worked on the sample data supplied on the vapor site! It seems like my CENTOS setup was just not compatible with whatever graphics resources were needed for isosurface and volume data. Glad to see that it worked on virtual Ubuntu though!
Hi Nathan,
Sorry for the late reply, and glad you have it working now. I looked at the output, and noticed this line “OpenGL vendor string: nouveau.” I could be wrong, but I think what it suggests is that your graphics driver is the open-source nouveau implementation instead of the Nvidia implementation. Volume Renderer and IsoSurface Renderer are very graphics heavy, so nouveau probably doesn’t do a very good job.
Please let us know if you have other issues!
