Thank Donnie Berkholz!
The ATI FireGL cards ouput left-view and right-view frame one after
the other, right?
But another type of stereoscopic TV need every frame interlacely warpped from
left-view and right-view like this:
LRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLR
a frame structure
So what does GL_STEREO in OpenGL mean? It means OpenGL
will render left-view and right-view frame one after the other, or
will render left-right warpped view frame? I did not find special
doc about it.
Another question is:
Is it a feasible way to modify mesa 3D to render left-right warpped
view frame by adding another instance of mesa context inside mesa?
One possible problem of this way is the performance I think.
Best regards,
linxs
