    Have you tried glGetBooleanv(GL_STEREO); to verify in code your hardware really supports Stereo ?

    Re: glutMainLoop

    Yes, It will render one time but your eyes will not have time to see it since the buffer is cleared immediately after (on the next frame).

    Thanks for these explanations. But I still don't understand why removing them is a good idea. Using DLs in some situations and VBOs in others would not be a perfect fit ?

    Re: keep the rendering on the window

    I'm not sure to understand your question ? To keep shape on the screen ? You need to draw your object (shape) each time, if that is your question.

    Yes they will remain normalized and correct if you perform translation or rotation on them.
