quote:"implementation that supports stereoscopic viewing has left and
right color buffers for the left and right sereo images."
"double-buffered systems have front and back buffers". does these two
sentence means that the four buffers are: front buffer, back buffer,
left buffer, right buffer? what about the front-left, front-right,
back-left, back-right mean? can someone give me a more detailed
explain on color buffer of opengl, thanks very much! |

The left and right buffers both have front/back. You
can do SwapBuffers on left and right independently.

while, is the two front buffers or the two back buffers independent?
and while opengl arrange its buffer so? |

Yes, all four are independent buffers. I don't understand your second
question.
