==== NVidia NVision 3D Setup ====
The NVidia 3D NVision setup provides a very nice 3D experience.  You need the following to enable PyMOL to show NVision 3D on Windows.  Please review the hardware and software requirements before moving on to the installation and setup.

=====Necessary Hardware=====
* Monitor: 120 Hz LCD: a [http://www.samsung.com/us/consumer/office/monitors/specialty/LS22CMFKFV/ZA/index.idx?pagetype=prd_detail&returnurl=|Samsung 2233RZ] or a [http://www.viewsonic.com/products/desktop-monitors/lcd/x-series/vx2265wm-fuhzion-lcd.htm|ViewSonic Fuhzion vx2265wm]
* Cable: [http://images.google.com/imgres?imgurl=http://www.logicsupply.com/images/dvi_connector_types.gif&imgrefurl=http://www.logicsupply.com/faq&usg=__G2BLaVTqBN4ie8fz_LJR1zc3zBc=&h=261&w=440&sz=15&hl=en&start=0&sig2=_hFM6ICIsxPq5WIAv8BCqg&zoom=1&tbnid=NIcKIs_BW_2rmM:&tbnh=135&tbnw=228&ei=KHN2TL-UC8P_lgfr44nsCw&prev=/images%3Fq%3Ddual%2Blink%2Bdvi%26hl%3Den%26biw%3D1475%26bih%3D1042%26gbv%3D2%26tbs%3Disch:1&itbs=1&iact=hc&vpx=136&vpy=323&dur=3153&hovh=173&hovw=292&tx=227&ty=74&oei=KHN2TL-UC8P_lgfr44nsCw&esq=1&page=1&ndsp=30&ved=1t:429,r:6,s:0 Dual Link DVI cable]; most  120Hz monitors will come with this cable--regardless, the cable is necessary
* Quadro Card: recent   [http://www.nvidia.com/page/quadrofx_family.html Quadro]   series graphics card (not a GeForce card) such as an FX 380 or 570 or later.  The GeForce cards do not support windowed openGL stereo, so we do not support these series of cards for the NVision 3D solution. For linux, you must have a quadro card that has a 3 pin mini din connector. The cheapest/oldest card that will work with linux is the Quadro 3700.
** '''WARNING''': The Quadro FX1400 does not support 3d vision stereo on Windows7 or Linux.
* Emitter: [http://www.nvidia.com/object/3d-vision-main.html|GeForce 3D Vision] hardware kit (an emitter with 3D shutter glasses). For Linux, make sure your kit comes with the 3 pin mini din "VESA" to 2.5mm stereo cable to connect from the stereo output on the video card into the emitter. See the [[3 pin Mini-DIN connector]] article for tips on how to make one of these cables if yours is missing. 
* GeForce Cards from series 400 onward have gained OpenGl support in recent Nvidia driver iterations (314+). This allows Pymol to be viewed in 3D using the quad buffered stereo setting with a GeForce card, 120Hz screen and 3D Vision kit.

=====Necessary Software=====
* Windows XP 32 bit (testing other OSs soon!), Windows Vista
* Latest Quadro [http://www.nvidia.com/Download/index.aspx?lang=en-us|Graphics Drivers from NVidia].
* Latest [http://www.nvidia.com/Download/index.aspx?lang=en-us|3D Graphics drivers for the NVision system]--under '''Product Type''' choose '''3D Vision'''.

=====Installation Instructions=====
======System Setup======
# Install the Quadro '''Graphics Drivers''' and reboot your machines
# Install the NVision Installation, hooking up the 3D emitter and glasses as directed in the instructions
## Make sure the 3D demos work
## Complete the '''3D Vision Drivers''' install (I had errors/warnings about old drivers but this did't matter)
# Specify how to drive the 3D by, click on
:::'''Windows Start Button''' > '''Control Panel''' > '''NVidia Control Panel''' > '''Manage 3D Settings''' (tab) > '''Global Settings''' (tab on the right) > '''Base Profile''' (tab).  Then, under '''Settings''' choose '''Stereo - Display Mode'''.  Next, select '''Generic Active Stereo (with NVidia IR Emitter)'''.  If you have a DLP monitor/TV choose the corresponding DLP option.  You '''must''' also set '''Stereo - Enable''' to '''on'''. 

======Running PyMOL======
That's it!  PyMOL should now work in Quad Buffered 3D Stereo using the NVidia 3D NVision system.  To run PyMOL in 3D mode on:
*Windows
:: '''Start > PyMOL > PyMOL > PyMOL 3D Launch (last menu option) > PyMOL Stereo (Quad Buffered 3D)'''
*Linux
:: pymol -S -t 1
:: ''Note that hardware stereo may not work in Xorg unless window compositing is turned off; Gnome3, Unity, etc all use window compositing as part of their eye candy. A window manager that should work by default is the MATE desktop. Install this if you have trouble''
* Mac
:: Sorry, at this time the NVision system is not known to work on Macs.
