# '''3D Vision Pro''' is ''not'' what you want, this is for professional CAD/CAM applications, and is expensive.<br />
# The quality of Nvidia 3D Vision 2 is better than that of Zalman, because Zalman stereo means halved vertical resolution.<br />
# The Nvidia 3D vision emitter must be connected to both USB and Quadro 3-pin DIN Stereo socket. This setup works on Windows and nowadays Linux (consult this [http://cismm.cs.unc.edu/core-projects/visualization-and-analysis/setting-up-a-simple-stereo-system/ link], and [http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html search this link for the word "USB"]. The cheapest (2014+) Nvidia Quadro with 3-pin DIN Stereo connector is the K4200 (http://www.nvidia.de/object/quadro-desktop-gpu-specs-de.html) which starts at ~ €700.<br />
# For Linux, a Nvidia 3D vision emitter "workaround" requires the DIN 3-pin connector found on the high end Quadros and [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses and emitter.<br />
# Compatible Stereo monitors (120 or 144Hz with DVI-I Dual-Link Connector (DVI-I DL / DVI-D)) for the above setups are [http://www.nvidia.com/object/3d-vision-displays.html listed] but this website has not been updated for years.<br />
# The currently most affordable NVIDIA 3D Vision solution on Linux (2013+ workaround) is to buy a monitor with built-in IR emitter (for example BenQ XL2420TX or ASUS VG278HR), and a cheap Quadro, e.g. the FX380 or K420. The latter has a Dual-Link DVI (DVI-D) and a Displayport outlet, so can drive the stereo monitor, and an additional monitor. This solution avoids the USB/3-pin hassle altogether. See below for xorg.conf! GeForce cards (instead of Quadro) ''do not give openGL Quad Buffered Stereo'' on Linux (on Windows neither).<br />
# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] also has not changed for years. http://geizhals.eu/?cat=monlcd19wide now has a "inkl. 3D-emitter" attribute. This currently only returns the Asus 278HR which can only be bought in Poland, or through EBay.<br />
# Cheap Quadros with DVI-I Dual-Link Connector (DVI-I DL / DVI-D) or DisplayPort work well. Make sure the card can do dual-link DVI if your monitor has only DVI-D input. Any card (including the "Windows only" ones!) [http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro listed] should work if a) it can do dual-link DVI if the monitor has only DVI-D input, and b) if the monitor has built-in emitter. DisplayPort works well with the BenQ XL2420TX.<br />
# For Quadros with DisplayPorts 1.2 only, you will need a Club-3D CAC-1051 active DisplayPort/Dual-Link DVI Adapter 330MHz (110 €: do not buy the cheaper 270 MHz model, it will not work because the bandwidth is too low for 1920x1080@120hz) or for cards with miniDisplay ports, the Club-3D CAC-1151 active miniDisplayPort/Dual-Link DVI Adapter 330MHz.<br />
# specs of latest ("Maxwell") and previous ("Kepler") generation of Quadro cards are at http://www.nvidia.com/object/quadro-desktop-gpus.html . A comparison of all PCIexpress Quadro cards is at http://en.wikipedia.org/wiki/Nvidia_Quadro#PCI_Express . Latest (2014+) with prices are at http://www.heise.de/preisvergleich/?cat=gra16_512&asd=on&asuch=quadro&xf=3312_2014&sort=p . Currently (2015), the K620 is the entry system with the best price/performance ratio; in the middle range the K2200 still seems affordable.<br />
<br />
== Software ==<br />
=== Linux ===<br />
[[Zalman Stereo]] is supported by [[Coot]]; no drivers or other software must be installed.<br />
<br />
NVidia 3D Vision 2: Using NVidia's 346.35 driver on RHEL/CentOS/SL 7, I changed /etc/X11/xorg.conf (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html) to have <br />
Section "Device"<br />
Driver "nvidia"<br />
Option "Stereo" "10"<br />
EndSection<br />
but there was no stereo (coot only shows a slightly rotated view), nor was there any hint in /var/log/Xorg.0.log that stereo is disabled. In fact, stereo ''is'' disabled, due to the Composite Extension (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xcompositeextension.html). If this extension is itself disabled by<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
then the login screen (gdm) crashes (discussed at https://devtalk.nvidia.com/default/topic/556113/3d-vision-and-composite-option). The only way out is to install a different display manager, like documented at e.g. http://jensd.be/?p=125 (confirmed by Dirk Kostrewa in 9/2014). This works well - I'm now using lightdm and the MATE desktop with a NVidia Quadro K420 and a BenQ XL2420TX. The graphics performance is very good for electron density inspection and fitting.<br />
<br />
===Mac OS X===<br />
The following command needs to be run for Macs to be able to support stereo in X11 programs, such as Coot [http://xanana.ucsc.edu/~wgscott/xtal/wiki/index.php/Installing_Coot_on_OS_X] :<br />
defaults write com.apple.x11 enable_stereo -bool true<br />
<br />
==Ono==<br />
You also need to set the environment variable STEREO for the stereo to work properly in ono:<br />
setenv STEREO on (tcsh)<br />
STEREO = on; export STEREO (bash)<br />
[http://dbb.urmc.rochester.edu/labs/wedekind/Wedekind-Lab/X-ray%20Lab/Methods/Nvidia-ONO.html]<br />
<br />
== Stereo on conventional CRT monitors ==<br />
<br />
Some of the NVidia Quadro cards support stereo. The cards that have an output called "stereo" under "Display Connectors" listed at [http://www.nvidia.com/object/IO_11761.html Nvidia's Quadro overview page] have a 3-pin DIN outlet that fits with [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses.<br />
<br />
The cheapest of these used to be the FX1400 (difficult to find these days, around 450 €), but now appears to be the FX3450 (around 750 €). These cards are by far fast enough for protein crystallography or modelling.<br />
<br />
For stereo, the xorg.conf might need the following lines<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
if the X log file (e.g. at /var/log/Xorg.0.log) says that stereo is not supported by composite.<br />
<br />
Another option that will be required in xorg.conf by programs running stereo is<br />
<br />
Section "Device"<br />
Driver "nvidia"<br />
Option "Stereo" "3"<br />
End Section<br />
<br />
For an example of how else to configure xorg.conf, see old versions of this article.<br />

# specs of latest ("Maxwell") and previous ("Kepler") generation of Quadro cards are at http://www.nvidia.com/object/quadro-desktop-gpus.html .

== Software ==<br />
=== Linux ===<br />
[[Zalman Stereo]] is supported by [[Coot]]; no drivers or other software must be installed.<br />
<br />
NVidia 3D Vision 2: Using NVidia's 346.35 driver on RHEL/CentOS/SL 7, I changed /etc/X11/xorg.conf (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html) to have <br />
Section "Device"<br />
Driver "nvidia"<br />
Option "Stereo" "10"<br />
EndSection<br />
but there was no stereo (coot only shows a slightly rotated view), nor was there any hint in /var/log/Xorg.0.log that stereo is disabled. In fact, stereo ''is'' disabled, due to the Composite Extension (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xcompositeextension.html). If this extension is itself disabled by<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
then the login screen (gdm) crashes (discussed at https://devtalk.nvidia.com/default/topic/556113/3d-vision-and-composite-option). The only way out is to install a different display manager, like documented at e.g. http://jensd.be/?p=125 (confirmed by Dirk Kostrewa in 9/2014). This works well - I'm now using lightdm and the MATE desktop with a NVidia Quadro K420 and a BenQ XL2420TX. The graphics performance is very good for electron density inspection and fitting.<br />
<br />
===Mac OS X===<br />
The following command needs to be run for Macs to be able to support stereo in X11 programs, such as Coot [http://xanana.ucsc.edu/~wgscott/xtal/wiki/index.php/Installing_Coot_on_OS_X] :<br />
defaults write com.apple.x11 enable_stereo -bool true<br />
<br />
==Ono==<br />
You also need to set the environment variable STEREO for the stereo to work properly in ono:<br />
setenv STEREO on (tcsh)<br />
STEREO = on; export STEREO (bash)<br />
[http://dbb.urmc.rochester.edu/labs/wedekind/Wedekind-Lab/X-ray%20Lab/Methods/Nvidia-ONO.html]<br />
<br />
== Stereo on conventional CRT monitors ==<br />
<br />
Some of the NVidia Quadro cards support stereo. The cards that have an output called "stereo" under "Display Connectors" listed at [http://www.nvidia.com/object/IO_11761.html Nvidia's Quadro overview page] have a 3-pin DIN outlet that fits with [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses.<br />
<br />
The cheapest of these used to be the FX1400 (difficult to find these days, around 450 €), but now appears to be the FX3450 (around 750 €). These cards are by far fast enough for protein crystallography or modelling.<br />
<br />
For stereo, the xorg.conf might need the following lines<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
if the X log file (e.g. at /var/log/Xorg.0.log) says that stereo is not supported by composite.<br />
<br />
Another option that will be required in xorg.conf by programs running stereo is<br />
<br />
Section "Device"<br />
Driver "nvidia"<br />
Option "Stereo" "3"<br />
End Section<br />

# The quality of Nvidia 3D Vision 2 is better than that of Zalman, because Zalman stereo means halved vertical resolution.<br />
# The Nvidia 3D vision emitter must be connected to both USB and Quadro 3-pin DIN Stereo socket. This setup works on Windows and nowadays Linux. The cheapest (2014+) Nvidia Quadro with 3-pin DIN Stereo connector is the K4200 (http://www.nvidia.de/object/quadro-desktop-gpu-specs-de.html) which starts at ~ €700.<br />
# For Linux, a Nvidia 3D vision emitter "workaround" requires the DIN 3-pin connector found on the high end Quadros and [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses and emitter.<br />

# The currently most affordable NVIDIA 3D Vision solution on Linux (2013+ workaround) is to buy a monitor with built-in IR emitter (for example BenQ XL2420TX or ASUS VG278HR), and a cheap Quadro, e.g. the FX380 or K420. The latter has a Dual-Link DVI (DVI-D) and a Displayport outlet, so can drive the stereo monitor, and an additional monitor. This solution avoids the USB/3-pin hassle altogether. See below for xorg.conf! GeForce cards (instead of Quadro) ''do not give openGL Quad Buffered Stereo'' on Linux (on Windows neither).<br />
# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] also has not changed for years. http://geizhals.eu/?cat=monlcd19wide now has a "inkl. 3D-emitter" attribute.

# '''3D Vision Pro''' is ''not'' what you want, this is for professional CAD/CAM applications, and is expensive.<br />
# The quality of Nvidia 3D Vision 2 is better than that of Zalman, because Zalman stereo means halved vertical resolution.<br />
# The Nvidia 3D vision emitter requires connection to both USB and Quadro 3-pin DIN Stereo connector. This setup only works on Windows, not Linux! The cheapest (2014+) Nvidia Quadro with 3-pin DIN Stereo connector is the K4200 (http://www.nvidia.de/object/quadro-desktop-gpu-specs-de.html) which starts at ~ €700.<br />
# Linux traditionally needs the DIN 3-pin connector found on the high end Quadros and [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses and emitter.<br />
# Compatible Stereo monitors (120 or 144Hz) for the above setups are [http://www.nvidia.com/object/3d-vision-displays.html listed] but this website has not been updated for years.<br />
# The currently most affordable NVIDIA 3D Vision solution on Linux (2013+ workaround) is to buy a monitor with built-in IR emitter (for example BenQ XL2420TX or ASUS VG278HR), and a cheap Quadro, e.g. the FX380 or K420. The latter has a Dual-Link DVI (DVI-D) and a Displayport outlet, so can drive the stereo monitor, and an additional monitor. This solution avoids the USB/3-pin hassle altogether. See below for xorg.conf! GeForce cards (instead of Quadro) ''do not give openGL Quad Buffered Stereo'' on Linux (on Windows neither).<br />
# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] also has not changed for years. http://geizhals.eu/?cat=monlcd19wide now has a "inkl. 3D-emitter" attribute. This currently only returns the Asus 278HR which can only be bought in Poland, or through EBay.<br />
# Cheap Quadros with DVI-I Dual-Link Connector (DVI-I DL / DVI-D) or DisplayPort work well. Make sure the card can do dual-link DVI if your monitor has only DVI-D input. Any card (including the "Windows only" ones!) [http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro listed] should work if a) it can do dual-link DVI if the monitor has only DVI-D input, and b) if the monitor has built-in emitter. DisplayPort works well with the BenQ XL2420TX.<br />
# If the Quadro has DisplayPorts 1.2 only, you will need a Club-3D CAC-1051 active DisplayPort/Dual-Link DVI Adapter 330MHz (110 €: do not buy the cheaper 270 MHz model, it will not work because the bandwidth is too low for 1920x1080@120hz) or for cards with miniDisplay ports, the Club-3D CAC-1151 active miniDisplayPort/Dual-Link DVI Adapter 330MHz.<br />
# specs of latest ("Maxwell") and previous ("Kepler") generation of Quadro cards are at http://www.nvidia.com/object/quadro-desktop-gpus.html . A comparison of all PCIexpress Quadro cards is at http://en.wikipedia.org/wiki/Nvidia_Quadro#PCI_Express . Latest (2014+) with prices are at http://www.heise.de/preisvergleich/?cat=gra16_512&asd=on&asuch=quadro&xf=3312_2014&sort=p . Currently (2015), the K620 is the entry system with the best price/performance ratio; in the middle range the K2200 still seems affordable.<br />
<br />
== Software ==<br />
=== Linux ===<br />
[[Zalman Stereo]] is supported by [[Coot]]; no drivers or other software must be installed.<br />
<br />
NVidia 3D Vision 2: Using NVidia's 346.35 driver on RHEL/CentOS/SL 7, I changed /etc/X11/xorg.conf (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html) to have <br />

Option "Stereo" "10"<br />
EndSection<br />
but there was no stereo (coot only shows a slightly rotated view), nor was there any hint in /var/log/Xorg.0.log that stereo is disabled. In fact, stereo ''is'' disabled, due to the Composite Extension (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xcompositeextension.html). If this extension is itself disabled by<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
then the login screen (gdm) crashes (discussed at https://devtalk.nvidia.com/default/topic/556113/3d-vision-and-composite-option). The only way out is to install a different display manager, like documented at e.g. http://jensd.be/?p=125 (confirmed by Dirk Kostrewa in 9/2014). This works well - I'm now using lightdm and the MATE desktop with a NVidia Quadro K420 and a BenQ XL2420TX. The graphics performance is very good for electron density inspection and fitting.<br />
<br />
===Mac OS X===<br />
The following command needs to be run for Macs to be able to support stereo in X11 programs, such as Coot [http://xanana.ucsc.edu/~wgscott/xtal/wiki/index.php/Installing_Coot_on_OS_X] :<br />
defaults write com.apple.x11 enable_stereo -bool true<br />
<br />
==Ono==<br />
You also need to set the environment variable STEREO for the stereo to work properly in ono:<br />
setenv STEREO on (tcsh)<br />
STEREO = on; export STEREO (bash)<br />
[http://dbb.urmc.rochester.edu/labs/wedekind/Wedekind-Lab/X-ray%20Lab/Methods/Nvidia-ONO.html]<br />
<br />
== Stereo on conventional CRT monitors ==<br />
<br />
Some of the NVidia Quadro cards support stereo. The cards that have an output called "stereo" under "Display Connectors" listed at [http://www.nvidia.com/object/IO_11761.html Nvidia's Quadro overview page] have a 3-pin DIN outlet that fits with [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses.<br />
<br />
The cheapest of these used to be the FX1400 (difficult to find these days, around 450 €), but now appears to be the FX3450 (around 750 €). These cards are by far fast enough for protein crystallography or modelling.<br />
<br />
For stereo, the xorg.conf might need the following lines<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
if the X log file (e.g. at /var/log/Xorg.0.log) says that stereo is not supported by composite.<br />

<br />
The cheapest of these used to be the FX1400 (difficult to find these days, around 450 €), but now appears to be the FX3450 (around 750 €). These cards are by far fast enough for protein crystallography or modelling.<br />

NVidia 3D Vision 2: Using NVidia's 346.35 driver on RHEL/CentOS/SL 7, I changed /etc/X11/xorg.conf (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xconfigoptions.html) to have <br />

but there was no stereo (coot only shows a slightly rotated view), nor was there any hint in /var/log/Xorg.0.log that stereo is disabled. In fact, stereo ''is'' disabled, due to the Composite Extension (see http://us.download.nvidia.com/XFree86/Linux-x86_64/346.35/README/xcompositeextension.html). If this extension is itself disabled by<br />

then the login screen (gdm) crashes (discussed at https://devtalk.nvidia.com/default/topic/556113/3d-vision-and-composite-option). The only way out is to install a different display manager, like documented at e.g. http://jensd.be/?p=125 (confirmed by Dirk Kostrewa in 9/2014). This works well - I'm now using lightdm and the MATE desktop with a NVidia Quadro K420 and a BenQ XL2420TX. The graphics performance is very good for electron density inspection and fitting.<br />
<br />
===Mac OS X===<br />
The following command needs to be run for Macs to be able to support stereo in X11 programs, such as Coot [http://xanana.ucsc.edu/~wgscott/xtal/wiki/index.php/Installing_Coot_on_OS_X] :<br />
defaults write com.apple.x11 enable_stereo -bool true<br />
<br />
==Ono==<br />
You also need to set the environment variable STEREO for the stereo to work properly in ono:<br />
setenv STEREO on (tcsh)<br />
STEREO = on; export STEREO (bash)<br />

<br />
== Stereo on conventional CRT monitors ==<br />
<br />
Some of the NVidia Quadro cards support stereo. The cards that have an output called "stereo" under "Display Connectors" listed at [http://www.nvidia.com/object/IO_11761.html Nvidia's Quadro overview page] have a 3-pin DIN outlet that fits with [http://www.nuvision3d.com/the60gx.html NuVision] or [http://www.reald-corporate.com/scientific CrystalEyes] stereo glasses.<br />
<br />
The cheapest of these used to be the FX1400 (difficult to find these days, around 450 €), but now appears to be the FX3450 (around 750 €). These cards are by far fast enough for protein crystallography or modelling.<br />
<br />
For stereo, the xorg.conf might need the following lines<br />
Section "Extensions"<br />
Option "Composite" "Disable"<br />
EndSection<br />
if the X log file (e.g. at /var/log/Xorg.0.log) says that stereo is not supported by composite.<br />
<br />
Another option that will be required in xorg.conf by programs running stereo is<br />
<br />
Section "Device"<br />
Driver "nvidia"<br />
Option "Stereo" "3"<br />

=== Nvidia 3D Vision 2 ===<br />
# '''3D Vision Pro''' is ''not'' what you want, this is for professional CAD/CAM applications, and is expensive.<br />
# The quality of Nvidia 3D Vision is better than that of Zalman, because Zalman stereo means halved vertical resolution.<br />
# The Nvidia 3D vision emitter that requires connection via USB and nvidia quadro 3-pin connector only works on Windows, not Linux!<br />
# Compatible stereo monitors without build-in emitter, thus windows only, are [http://www.nvidia.com/object/3d-vision-displays.html listed] but this website has not been updated for years.<br />
# Linux needs the DIN 3-pin connector which is only on the high end Quadro cards. The cheapest (2014+) Nvidia Quadro with 3-pin DIN Stereo connector is the K4200 (http://www.nvidia.de/object/quadro-desktop-gpu-specs-de.html) which starts at ~ €700.<br />
# The currently (2013+) most affordable NVIDIA 3D Vision 2 solution on Linux is to buy one of the monitors with built-in IR emitter (we have the BenQ XL2420TX), and a cheap Quadro, e.g. (2013) the FX380 or (2015) K420. The latter has a Dual-Link DVI and a Displayport outlet, so can drive the stereo monitor, and an additional monitor. This solution avoids the USB/3-pin hassle altogether. See below for xorg.conf! GeForce cards (instead of Quadro) ''do not give Stereo'' on Linux.<br />
# [http://www.nvidia.com/object/3d-vision-displays.html The Nvidia page that names monitors with built-in emitter] also has not changed for years. http://geizhals.eu/?cat=monlcd19wide now has a "inkl. 3D-emitter" attribute. This currently only returns the Asus 278HR which can only be bought in Poland, or through EBay.<br />
# cheap Quadro cards with dual-link DVI-D or DisplayPort work well. Make sure the card can do dual-link DVI if your monitor has only DVI input. Any card (including the "Windows only" ones!) [http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro listed] should work if a) it can do dual-link DVI if the monitor has only DVI input, and b) if the monitor has built-in emitter. DisplayPort works well with the BenQ XL2420TX.<br />
