[Paraview-developers] [EXTERNAL] Re: osmesa version of ParaView

[Scott, W Alan]

So, just to be really clear (I got a bit confused here…) I am on a Linux box, such as my local blade or Linux workstation.  I want to test a remote Paraview install, or my data is on a remote Linux server (and I want to run a standalone version of ParaView).  I want to do the following:

ssh -X (or ssh -Y)
paraview –magicFlagsGoHere

and it just works on a remote Linux box that does not allow a GLX context.

Thanks,

alan

Couple quick thoughts

If we can connect to the remote display using GLX (but not forwarded) then we can render remotely (offscreen but using normal OpenGL) and then copy the result to an Xwindow which is forwarded to a local machine. Sort of a RenderingDisplay=:0.0 Display=:1.0 where 1.0 is the forwarded one.

I recall there being an issue with osmesa and accelerated opengl in the same binary but I have very limited experience with it.

Cory/ Utkarsh/ Guys,
I think we need to be able to build an osmesa version of ParaView, and we need this rendering option as a command line option for all Kitware Linux downloads.  The reason is that the next version of Redhat – RHEL 7 will no longer allow the forwarding of GLX contexts.  Thus, to be able to X forward ParaView back to a local computer, we will need to render into only an X window.  This is already giving us issues at Sandia with new Linux installs.

Is this possible?  How hard will it be?  Any ideas on schedule?

Before I write this up as a bug, I figured I would see what type of discussion we get in this thread.

Thanks,

Alan
