"The NVision3D API does allow you to blit images for specific eyes (this is meant for movie players and image viewers). But it also allows you to emulate quadbuffer stereo: Instead of GL_BACK_LEFT and GL_BACK_RIGHT buffers create two Framebuffer Objects, which you bind and use as if they were quadbuffer stereo. Then after rendering you blit the resulting images (as textures) to the NVision3D API." "With only as little as 50 lines of management code you can build a program that seamlessly works on both NVision3D as well as quadbuffer stereo. What NVidia does is pointless and they should just stop it now and properly support quadbuffer stereo pixelformats on consumer GPUs as well." Is this true and could code be added to PyMol to allow GTX cards to provide 3D for PyMol?

The monitors were bundled with Nvidia 3D vision v2 glasses. We have Quadro FX5800 cards, but we do NOT use the 3-pin stereo port, but rather the built-in emitter in the monitors. I have pasted my notes from the installation below. Is works with PyMOL as well as other OpenGL applications, such as VMD, Accelrys Discovery studio, CCDC GOLD/Hermes, Yasara, etc. > Cheers, > > Esben > > Asus VG278H flat panel 3D screens and Ubuntu 12.04 > These screens have built-in emitters that actually work under Linux, with Nvidia drivers version 310 or newer.

Now check if stereo works. If so, then switch back to the text console and kill the X-server (Ctrl-C). The restart lightdm and login from the graphical login screen.

I'm not sure if I need to be more specific than that (if there are particular cards/monitors that are known to work/not work). I'm also not quite sure if this is possible on Windows 7.
