[Paraview] [EXTERNAL] Off screen rendering

Yup, that'd be the place. Also

vtkSMRenderViewProxy::CaptureWindowInternal(). There it determines if offscreen rendering should be used too.

OK, I am a little further along.  I believe this logic is set up in vtkOpenGLRenderWindow.cxx, possibly in CreateHardwareOffScreenWindow().   Assuming I am hardware rendered on the client side (not Mesa3d), am I correct that I need GL_ARB_texture_non_power_of_two or  GL_ARB_texture_rectangle, and GL_EXT_packed_depth_stencil?  Is there a simple location this logic is documented?

Next, is this the correct place to put a debugger, in case no one knows?

Thanks!

I have a user that is having problems with Save Animation.  Although it is selected in Settings, it appears that off screen is not being turned on.  This is Linux, remote server.

What are the rules that ParaView uses to decide if off screen rendering may be used?  Is it more complex than just what the user wants?  Is this documented somewhere?

Thanks!
