Hi Clemens,
I have a workstation running under Rocky Linux 8 with a Nvidia RTX A4000
graphics card plus the bracket for the 3-pin mini-DIN connection. The
last Nvidia driver that both recognizes and activates the Nvidia 3D
Vision IR emitter is the 525 driver which can be installed from the
Nvidia CUDA 12.0 repository for Linux. Since driver version 530, the
Nvidia emitter is recognized, but is not activated anymore upon
switching to 3D stereo.
Best regards,
Dirk

There will be no alternative to quad-buffered OpenGL if you want broad
support of all stereo-capable software. In fact, quad-buffered OpenGL
is part of the OpenGL specification since the beginning. The Acer
website says that the SpatialLabs displays require an additional,
dedicated driver. It seems rather unlikely that this will enable
quad-buffered OpenGL.
A few years ago, when our 3D vision equipment (which, of
course, supported quad-buffered OpenGL) stopped working properly after
a driver update, I had a long conversation with a technical guy from
Nvidia. He told me that there would be no bug fixes for 3D Vision
anymore and that driver support would be discontinued soon. From the
conversation here, it seems however, that 3D vision is still in use
(with newer drivers?) - could you please post the driver version that
works for you?
The Nvidia technician also said that quad-buffered OpenGL support will
continue for professional cards (which I can confirm for the latest
driver and our dual-monitor stereo display). Since then, we have kept
the 3D Vision glasses and monitors, but have never tried to see if
they can be reactivated with a current driver ...
Best,
Clemens

Strengths and weaknesses.
The AcerSpatialLabsStereoscopic 3D-solutions are lenticular displays.
Such solutions have existed for quite a while, so it's nothing new.
They just claim to do it better by using "AI."
Lenticular displays do not require glasses. They have lenses/prisms
(made of liquid crystals) in front of the pixels, so that of each pair
of pixels, one is seen by the left eye and one by the right eye.
To do this successfully, the display needs to know where your eyes
are, to shape the prisms properly. That is purportedly where the AI
comes in. Only one person can view the screen with this 3D effect at a
time.
Lenticular displays halve the resolution in one spatial dimension.
---
For comparison, the old CrystalEyes and Nvidia 3D systems use active
glasses: the lenses of the glasses are shutters made of liquid
crystals. One shutter is open and one closed, synchronized to the
display. Left and right images are interlaced to the display in the
time dimension.
To do this successfully, the display needs to be bright enough. It
also needs to have a refresh rate of at least 120 Hz so that each eye
can get 60 Hz viewing. But you get the full spatial resolution of the
display.
Wearing the glasses, and keeping them charged is somewhat of a
nuisance. But as many people can view the display at one time as the
number of pairs of glasses you have.

Hi,
could Acer's newly developed SpatialLabsStereoscopic 3D-solutions i.e.
3D-monitors offer a way out? Apparently, with the aid of AI, they
claim it can transform 2D to 3D content.
3D is still alive as CAD and game software developers are currently
opting for 3D-glasses-free viewing based on OpenXR or SteamVR…
Best

Dear all,
I have just been shocked by our IT department’s announcement that
they will force us into migration to Win11 very soon. I know I am
a dinosaur, but I still use and love my old nvidia
Quadro/Asus/shutter glasses combi (over 10 years old) for hardware
stereo viewing of protein structures under Win10. I am afraid that
this will simply not work anymore once I have been upgraded, since
nvdia has disabled hardware stereo in its drivers long time ago.
Personally, I cannot understand how modern structural biology can
live without it and I would love to still be able view structures
in “real” 3D.
I know that the ccp4 community is graphics- and tech-savvy, I am
therefore asking if you know of any modern day and
established/sustainable hardware solution for 3D viewing in our
favorite programs (Coot, PyMol, …).
Thank you in advance for your advice,
Wulf
