[Paraview] [Non-DoD Source] Building Paraview with OSMESA

[Christopher Neal]

Thanks Rick!

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/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.”

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:
pvserver –use-offscreen-rendering TestScript.py

Stupid question – when you start up the pvserver process, are you passing it the “—use-offscreen-rendering” flag?    

 

mpirun –np 8 pvserver —use-offscreen-rendering …….

 

What’s your build platform?  I have lots and lots of build scripts I can share!

Hi All,

 

I’ve been trying to compile a version of ParaView that uses osMesa. I’ve tried to follow the process that is explained on the wiki (Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D < Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D >  ), 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?  

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?


Thank you,

Chris N
