Hi,

I asked this question several times but never got a answer. My problem is
stereo in Performer in a X Window.

 - I use STR_BOT to switch to stereo mode

 - open a pfPipeWindow and set the type to
        pfPWinType(pw, PFPWIN_TYPE_X);

 - choose a framebuffer configuration
        pfChoosePWinFBConfig(pw, FBAttr) with
           FBAttr[] = {PFFB_RGBA, PFFB_DOUBLEBUFFER, PFFB_STEREO, NULL};

 - init the two channels

 - init the view with the view offsets

 - in the PreDraw-Callback I set alternating
        XSGISetStereoBuffer(xdisplay, glWindow, STEREO_BUFFER_LEFT);
        XSGISetStereoBuffer(xdisplay, glWindow, STEREO_BUFFER_RIGHT);

It seems that XSGISetStereoBuffer doesn't have any effect because I only see
the leftbuffer.

Is there anybody who has a working PERFORMER program with stereo in a X window?
(I only have examples in GL and OpenGL).

Any idea what I'm doing wrong or if there is a bug in the framebuffer
configuration for the pfPipeWindow of type X ?

Thanks for any help

Daniela
