I would to use GLX Pixmap(or Pixel buffer) with Performer
to make a fast offscreen rendering.
I don't want to use pfWindow because I don't see how
I can use it easily with any scene-graphs (or pfScene
or pfChannel).
So, it seems that using a pfPipeWindow should be a
good way to solve this kind of problem.
In fact, we can set the right drawable (setWSDrawable(,) )
with a GLX Pixmap (or a GLXPBufferSGIX ) but in all cases,
Performer shows our pfPipeWindow. We can't have a PFWIN_TYPE_NOPORT
when we use a pfPipeWindow.
Does someone know how to make "real Offscreen rendering" with
Performer ? (i.e. without to redefine a new traversal of scene-
-graph to draw it, and without to see the window (open automaticaly
with the first drawing)).
Should we ever have to see a window for offscreen rendering with
Performer ? Is it a limitation of Performer ?
Thanks in advance for any answers.
Yann Argotti.
