That's actually not that difficult to implement. (I think). Jmol now just renders two images, assuming into the same bitmap. It would just have to put pixels in different columns! Only thing is that Jmol needs to figure out if the first Jmol bitmap buffer column is a even or uneven column on screen... and correct for this by either taking +5 or -5 angle. > [Miguel, if you implement what I've described above, I can test & > troubleshoot it -- or you could stop by some evening if you're still > visiting the bay area with regularity.] > > I am curious the know whether or not g3d will be able to create a stereo > pair that is as effective as hardware OpenGL.

We'll see! I've seen in the doc demo that resolution was low resulting in having a harder time to focus on the 3D image... anti-aliasing helps here... but I assume that g3d can still apply antialiasing to each frame separately...
