i am working on programing with opengl &
vc++.now i have a question about the using of stero buffer.that is
to say,i nees to display two images on the monitor alternatively on
the Asus v3800(with a stero glasses).

I have try it several times.it does
not working.

this is part of my code.

PIXELFORMATDESCRIPTOR pfd =
{
sizeof(PIXELFORMATDESCRIPTOR), // size of this pfd
1, // version number
PFD_DRAW_TO_WINDOW| // support window
PFD_SUPPORT_OPENGL| // support OpenGL
// PFD_DOUBLEBUFFER|
PFD_STEREO,
PFD_TYPE_RGBA, // RGBA type
24, // 24-bit color depth
0, 0, 0, 0, 0, 0, // color bits ignored
0, // no alpha buffer
0, // shift bit ignored
0, 0, 0, 0, // accum bits ignored
32, // 32-bit z-buffer
0, // no stencil buffer
0, // no auxiliary buffer
PFD_MAIN_PLANE, // main layer
0, // reserved
0, 0, 0 // layer masks ignored
};

void CTest1View::OnMyshow()
{
// TODO: Add your command handler code here
HWND hWnd=GetSafeHwnd();
HDC hDC=::GetDC(hWnd);
wglMakeCurrent(hDC,hglrc);
myinit();
mydisplay(image1,image2);

wglMakeCurrent(NULL,NULL);
SwapBuffers(hDC);

}

..
..
..
void CTest1View::mydisplay(unsigned char *image1,unsigned char *image2)
{

for(int i=0;i<20;i++)
{
glDrawBuffer(GL_LEFT);
// glColorMask(1.0,1.0,1.0,1.0);
// glRasterPos2i(0.0,10);
glDrawPixels(DrawWidth1,DrawHeight1,GL_RGB,GL_UNSI GNED_BYTE,image1);


glDrawBuffer(GL_RIGHT);
// glColorMask(1.0,1.0,1.0,1.0);
// glRasterPos2i(100.0,10);
glDrawPixels(DrawWidth1,DrawHeight1,GL_RGB,GL_UNSI GNED_BYTE,image2);
glFlush();


}
}

hey, aren't the 2 images for stereo glasses generated in drivers, totally transparent to the program? Otherwise every program would have to be coded for the glasses, which isn't the case. My Elsa Revalator glasses work this way, anyway.

Asus board dso not have OpenGl stereoscopy
implemented in the way you are tring to inicaliaze. Have a look on www.stereographics.com (http://www.stereographics.com) for graphic cards witch supports PFD_STERO in pixelformatdescriptor
