Hi Jonathan,
I didn't find any technical descriptions of what 3D software will work with the Asus laptop lenticular display. I major downfall of this kind of autostereo display that requires no glasses is that software has to have special code to render to it. Here's an example of ChimeraX on a LookingGlass autostereo display where I wrote that special rendering code:
As Greg mentioned lenticular displays usually use vertical strips of pixels for your left eye and for your right eye. If the lenticular lens has 12 viewing directions then you get 1/12 pixels in each image so the resolution is much worse than the underlying flat panel display. Asus says they use eye tracking, so it may be that software only has to render two of those strips since it knows where your eyes are. But they say it can also work with two viewers, so maybe the 3D software needs to be able 4 views. If it can work with just two views then it might be able to handle 3D software that offers VR support or side-by-side stereo (it won't work with sequential stereo since the Nvidia RTX 4070 GPU in these laptops can't do sequential stereo).
The only way to know how well it works with ChimeraX is to try it. If someone tries it please post a review on the ChimeraX mailing list. Be prepared for disappointment. The Asus marketing is full of deceptive hype -- almost every image shows some 3D model popping out of the laptop screen that is bigger than the screen. That is pure nonsense. Any 3D effect will be limited to the very small intersection of the two cones from your two eyes to the rectangular screen.

Example of the Asus dishonest marketing of the 3D laptop display. That figure popping out of the display would have to be 2 times smaller in order to fit in the overlap region between the viewer's eyes and the screen.

I'm always on the lookout for new options for 3D stereo displayhardware (Chimera or Chimerax). I just saw this Asus system withglasses-free stereo, using eye-tracking cameras and a lenticularscreen. It looks to me like a premium OLED laptop targeted to gamersand CAD designers. I'm unfamiliar with Asus Spatial Vision and AcerSpatialLabs, but one reviewer said that it works with multiple peopleviewing it- I'm slightly sceptical. :-)https://arstechnica.com/gadgets/2023/01/asus-new-16-inch-workstation-laptops-have-3d-oled-screens/Tom, you suggested that VR headsets were the best option a few yearsago. What are your thoughts about this release? (Replies from non-Tomindividuals are also welcomed.)Thanks!-JonathanOn Thu, Jun 13, 2019 at 10:32 PM Jonathan Sheehan<jonathan.sheehan@gmail.com> wrote:
Thanks for the information, Tom- I was hoping somebody had better
news. It sounds like we're in a dead zone between the epochs of stereo
glasses and VR headsets.
I suppose I'll have to start looking into VR systems.
Thanks,

Hi Jonathan,
Nvidia was the main distributor of 3D active LCD stereo glasses, and they dropped support for their Nvidia 3D Vision glasses and emitters in April 2019 as described here
https://www.ghacks.net/2019/03/11/nvidia-3d-vision-end-of-support/
https://nvidia.custhelp.com/app/answers/detail/a_id/4781
Nvidia graphics driver released after April 2019 won't work with these glasses. You can continue to use Nvidia 3D Vision with old graphics drivers, maybe that is the best option.
The LCD active stereo glasses technology appears to be nearly dead. If you try to use it be prepared for problems getting it to work and to pay a lot of money. We have been using active stereo LCD with a stereo projector for many decades. We use it infrequently now, instead using virtual reality headsets with our ChimeraX software. Virtual reality headsets give better immersion but don't yet easily handle having a half-dozen people viewing the same scene in the same room (would require 6 separate computers driving the 6 headsets).
Here are details on the old LCD glasses projector system we are have which is working:
10 pairs of RealD CE4 and CE4s stereo glasses ($280 each)
http://www.colorlinkjapan.com/brand/product/ce4s.html
A Stereo Graphics EXXR extra long range emitter ($780)
http://www.colorlinkjapan.com/brand/product/exxr-emitter.html
A Christie Mirage S+4K projector circa 2006, (1440 x 1050 resolution), no longer in production

An Nvidia Quadro P6000 graphics card ($3700)
https://www.amazon.com/PNY-Quadro-P6000-Graphic-Card-x/dp/B01M0S2FKR
with a stereo emitter bracket
http://www8.hp.com/h20195/v2/GetPDF.aspx/c04658472.pdf
This system breaks about once a year after graphics driver updates, the fix usually being to set the projector to be either the primary display or secondary display (depends on graphics driver version). Also the glasses fail at maybe the rate of 1 out of 10 pairs per year.

Hi all,
What stereo setup are people recommending these days? It seems that
NVIDIA has discontinued the 3D Vision 2 goggles+emitter. Is there
something else that is available and works well?
Thanks for any advice!
-Jonathan
