OpenGL, seen with 3D glasses

[Nathalie Pochet]

Hi,

I have a graphics card with 3D glasses (Asus V7700). I would like to
visualise 3D objects in OpenGL so that you can see it with the 3D
glasses. In the Asus-manual, it's written that OpenGL is supported with
"interlacing mode" as well as with "page flipping mode".

I found several examples about "stereo" on the internet, but I suppose
the graphics card doesn't support "stereo mode", because they all give
the same errors: "GLUT: Fatal Error in ...: pixel format with necessary
capabilities not found.", "GL_STEREO flag set to FALSE, indicating that
stereo should not be supported" and "The application window's pixel
format failed to switch to stereo mode". You can find one of the
examples on the following site:
http://www.swin.edu.au/astronomy/pbourke/opengl/stereogl/ . My glut is
version 3.7.3.

So I suppose that I'll have to try "interlacing mode" or "page flipping
mode" in OpenGL. But I don't know how I should do this.

Does anyone know which mode I should do and how I could do that?
And does anyone has got examples?

Thank you very much!

page flipping mode and interlaced mode are drawing modes, nothing to do with
stereo. I don't understand why they'd say it supports page flipping, that's
like saying it supports 640X480. DUH!

for stereo... try activating VR or stereoscopic mode in the driver settings.
make sure you have the latest drivers

We have got the same glasses here, but we have not been able to get them to
work with OpenGL. It works with Direct3D though. Anyway the 3d effect is
only a driver hack and it has nothing to do with the GL_STEREO flag. We have
used similar ELSA shutter glasses (Revelator) , which worked with OpenGL.
You did not have to set the GL_STEREO flag and render to two different back
buffers. The drivers for these glasses don't work with GFORCE based graphics
card though (we have only been able to run OpenGL stereo with a TNT2 based
Elsa card)

Nathalie,

Your graphics card does not support stereomode. When using the glasses your
graphics card driver allows you to switch on the glass option. When this
happens, the graphics card renders 3D images two times moving the camera a
little bit (this amount is also configurable in the driver options). This is
why the programs run slower (they have to render each frame two times). When
rendering the left image the graphics card sends a signal to the glasses to
polarize the right glass and the same with the right image. This is why you
see the images darker. Your right eye is just getting the right image and
the left eye the left one so your brain thinks that the image is 3D.
So you should view normal OGL fullscreen programs in 3D, but not stereomode
programs.

Hope this helps.
