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.

Subject: Re: [ccp4bb] 3D/Stereoscopic hardware options in 2025?
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
