Hi,
I'm trying to render with Performer a scene in an off-screen buffer (PBuffer).
Linux (mdk 9.0), Performer 3.0 but it didn't work on Performer 2.5 as well.
GeForce 4 (Ti4600)
I've already send an email about that 3 months ago but I still have the problem
and I can not believe that nobody use the off-screen rendering on Linux!!
Because it doesn't work, until now I've used a window to do this off-screen rendering
but I would like a better solution!
The Performer example /usr/share/Performer/src/pguide/libpf/C/pbuffer.c
doesn't work and crash with this message :
> PF Warning/Usage: pfWindow::open - window of type PFWIN_TYPE_PBUFFER -
> required GLXFBConfig is NULL - set with ::setFBConfig.
But setFBConfig is called!!
So my other solution would be to open a PBuffer without Performer (it works) but
then how can I say to Performer to render the scene into this PBuffer?
If someone has an example of off-screen rendering on Linux, I would appreciate.
Thanks,
Alex
