Thanks to Christoph and Jeroen!

This was the perfect resource to make it work.

Cheers,

Subject: Re: [PyMOL] Stereo Set up with PyMOL v1.7.4.4 EDU

Dear Chris,

We have  a similar setup using an older Quadro card employing a dual screen output (one DP/DVI-port for each projector). The two "screens" are in "clone mode" (NVIDIA control panel), as described e.h. here:

http://nvidia.custhelp.com/app/answers/detail/a_id/3012/~/how-to-configure-passive-or-dual-pipe-stereo-with-quadro-cards-in-windows-7.

The projectors are aligned using a projector-built-in test pattern.

In the NVIDIA 3D settings you have to activate 'Stereo' using the 'NVidia Clone Mode Stereo' (or similarly named). In PyMol you use the 'Quad-buffered Stereo' option. The NVIDIA driver will do the rest to provide the individual left/right images. It works for full screen and also for windowed PyMol (OpenGL windows with activated stereo only). The rest of the desktop remains "cloned".

Hope this helps,
Christoph

Hi All,

We "upgraded" our 3D viewing room with a computer that has a Quadro K2000 video card running Windows 7.  The computer displays through two NEC projectors with polarizing filters that display agains a special screen.  Stereo is viewed through polarized glasses just like in the movie theater.   We had the stereo working a couple years ago, but it stopped with the upgrade.  Here is my question:

Are there any special Quadro settings I need to set to have the video card play nice with PyMOL?
Which stereo_mode do I set for this type of setup?  I ran through all the options (1 - 12), but none caused the appropriate stereo effect
Am I restricted to full screen mode or can I run stereo in windowed mode?  We only tried Windowed mode.
Does the stereo_mode change if I am using full screen mode versus window mode?

Any help or resources you can point me to would be greatly appreciated.  (Proper procedure for aligning the projectors would be greatly appreciated.  They are fairly well aligned centrally, but become blurry from misalignment at the edges.)

Your help is greatly appreciated.

Cheers,

Chris
