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 699-50764-0000-001 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).
Regards,
Pedro

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.
Zhuang

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 --> <choose your graphics cards
- for my laptop it is Quadro K5000M>
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 chance trying to use "Nvidia Vision" glasses with an
usb-emitter to view the 3D output? This option is no longer supported
with the newer nvidia drivers....

Hi guys,
When I switched mono to hardware stereo, my coot window stuck. I
tried 0.9.7 0.9.6 0.8.7, they look all the same. I used an AMD CPU
and Quadro P620 card, and the hardware setup is working for PyMOL
and UCSF Chimera.
Please see screenshot as attached, and any input would be appreciated.
