Hello Yong,

concerning the driver problematics, anybody interested can find more 
information on 
"https://nvidia.custhelp.com/app/answers/detail/a_id/4845/~/3d-vision-end-of-life---faq; 
  where nvidia makes for example the following statements:


1) R418 graphics drivers will be the last driver to contain the 3D 
Vision driver package. The R418 branch will be supported until January 2020.


2) NVIDIA will decouple the 3D Vision USB driver from the graphics 
driver. NVIDIA will provide the 3D Vision USB driver package as a 
separate installer on NVIDIA.com   .    This will allow users to 
upgrade the graphics driver while continuing to use the standalone 3D 
Vision USB driver.


So one can upgrade the windows driver for the GPU only but will need a 
stand-alone 3D Vision driver as explained.


Some people are trying to solve the "Linux problem" by reverse 
engineering, see http://www.open-terrain.org/index.php/Projects/3DVision 
 But as you noted, the 3D Vision kit is history.


Concerning Epiphany, not sure you can still purchase this brand. Seems 
there are only few companies left that produce shutter glasses and 
emitters. One of them is XPAND https://xpandvision.com which is well 
known and produces glasses for Sony, NEC and other brands. They also 
sell emitters that come with a 3-pin DIN stereo plug for connecting 
directly to the GPU or bracket. I think the prices for the glasses are 
okay if compared to the original Streographics Crystal Eyes 3D glasses, 
see http://www.ultimate3dheaven.com/stcrey33dgl3.html.

The discontinuation of support for 3D Vision in the driver actually 
does not impair the use of stereo as quad buffered stereo is still 
supported.  Use of driver beyond 390.41 is fine.  Sometimes you are 
forced to use the latest version because of some other 
incompatibility.  The trouble is with the hardware support, no more 3D 
Vision hardware kit.  An important piece of information from Zhuang is 
the hardware “from a not-so-often-heard vendor called epiphany”. 
Anybody else has good experience with this vendor?  I don’t see 3D 
glasses or emitter from their catalog.

Hi Pedro,

Zhuang's problem was finally solved by installation of the latest 
nvidia graphics card driver 511.79.


WinCoot works on windows 10, no doubt: Nvidia however stopped 
supporting the 3D Vision kit from within (professional) graphics 
drivers and instead offers a stand-alone separate 3D Vision driver 
390.41 that will not be updated in the future (only in case of 
security issues). So, how long this work-around will be useful is 
unknown. For the future this means, one probably needs to purchase 
the much more expensive GPUs...


For linux, there is an absolute requirement for the 3-pin connector 
(either build-in or attachable via bracket) as the USB-based 3D Vision 
kit was never actively supported by Nvidia under linux (and that is 
indeed a commercial decision...).


"Specs" will not help to select the GPU as even the small P400 or P620 
offers - according to specs - 3D quad-buffered openGL stereo support 
(that is, under Windows and making use of the 3D Vision kit). What you 
need under Linux is an nvidia GPU with an on-board 3-pin DIN stereo 
connector or, a GPU with a connector for the 3-pin DIN stereo bracket 
(NVIDIA 699-50764--001 or PNY 930-50764). So, for the GPU, one 
needs to pick a second hand model such as K / M /P4000, or newer 
models such as rtx 4000 or rtx a4000 (a2000 will not work)...


Cheers,

Jeroen

Hi there,

Coot stereo not working under Windows is a common problem. There
seems to be a driver incompatibility that causes the issues you
described. In our lab, we were able to use Coot stereo only under
Windows 7, not on later Windows versions.

As for the Linux hardware you do need a more expensive graphics
card - as far as I know there is no technical reason for the 3-pin
connector requirement and it may be just a commercial decision by
NVIDIA to require this. However, since NVIDIA discontinued the 3D
Vision support these cards may be more difficult ro obtain.
Basically you need a NVIDIA Quadro K4000, similar or higher specs
- it should support 3D Vision stereo (maybe this is indicated in
the specs and/or in the box).

Hi Jeroen,
Thank you so much for your response. I use a Win10 pro with Nvidia graphics 
driver 442.92 and 3D vision controller driver 390.41, and BenQ XL2411P 3D 
monitor. The IR emitter is connected to the computer only via USB, and together 
with 3D glasses, was from a not-so-often-heard vendor called epiphan.  It works 
pretty fine in UCSF chimera and PyMOL, so I assume the hardware and software 
configuration is correct. I did enable the stereo mode in Nvidia control panel.
This is the first time I setup a 3D work environment, and I used Win10 to make 
thing less complicated. Next time I would like to set up 3D workstation in 
Linux. Could you please kindly provide the hardware list that is guaranteed 
working with Linux? Could you please clarify what a 3-PIN connector is and how 
is it making things different?
Thank you in advance.

Please also check the following..



  1.  On Windows 10, make sure “3D display mode” is set to “On” in Windows 
settings: Settings --> Display --> Advanced
  2.  Make sure OpenGL is turned on: --> Manage 3D Settings --> Global Presets 
--> OpenGL rendering GPU --> 
  3.  Make sure Stereo is turned on: --> Manage 3D Settings --> Global Presets 
--> Stereo - Enabled >
  4.  if steps 1-3 do not help, rollback the driver: 12/29/2016 Version 
21.21.13.7654

More info would be good

What windows version?
What nvidia driver version?
Monitor type?
Quadro P620? This one does not have a 3-pin connector for signal output

Are you by any
