Here’s an example OS_Mesa/cmake command used on one of our generic RHEL6 systems. With this build, we throw the “—use-offscreen-rendering” flag when we fire up the pvserver. I think that the critical flags are “osmesa=ON, mesa=OFF, qt=OFF” ….. Can you use your current build in a traditional client-server configuration to verify that the OS_Mesa is built correctly? That might make it easier to narrow down to a build issue or a Catalyst issue.

I’m running OpenSuse 13.2 64bit. I’m not explicitly starting a pvserver, because I’m running one of the C++ Catalyst examples, which is located at ParaView/Examples/Catalyst/<wbr>CxxFullExample. That is mainly what is confusing me. I’m not sure if I built ParaView
with osMesa incorrectly, or if that Catalyst example is somehow just telling ParaView ‘Hey, don’t use the offscreen rendering stuff, just go ahead and keep rendering to the screen.”<br><br>
I’m thinking that I should be able to test the offscreen rendering capability independently of that Catalyst example by generating a Python trace of a pipeline that creates an image output, and the running it with a command like:<br>

), but I haven’t been able to get ParaView to render offscreen. I don’t have build errors, but when I run something that saves a screenshot I still see a window pop up on my screen. Would anyone be willing to share their configuration script/command that they
use for compiling ParaView with osMESA? <br><span class=""><br>
Also – If I have a python script that creates a screenshot of some geometry, do I need to edit it in any way before running it with a version of ParaView that uses osMesa? Or is all of that handled behind the scenes?<br><br><br>
