I read that it is a lenticular display. So multiple viewers would be fine. Normally, to generate a 3D lenticular image you need lots of source images, at least 12 if I remember correctly. And I have a vague recollection that there was a 3D lenticulary display at SIGGRAPH many years ago that needed 24 source images. 3D stereo and VR only need 2 source images. So the computational requirements are probably significantly greater that for VR. And that means that the size of the 3D models you can view will be correspondingly smaller. Maybe the eye tracking can mitigate the extra computational needs. We need to learn more the API to say more. HTH, Greg On 1/6/2023 1:38 PM, Jonathan Sheehan via ChimeraX-users wrote:
I'm always on the lookout for new options for 3D stereo display hardware (Chimera or Chimerax). I just saw this Asus system with glasses-free stereo, using eye-tracking cameras and a lenticular screen. It looks to me like a premium OLED laptop targeted to gamers and CAD designers. I'm unfamiliar with Asus Spatial Vision and Acer SpatialLabs, but one reviewer said that it works with multiple people viewing it- I'm slightly sceptical. :-)

Tom, you suggested that VR headsets were the best option a few years ago. What are your thoughts about this release? (Replies from non-Tom individuals are also welcomed.)
Thanks! -Jonathan

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, -Jonathan

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

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)

A Stereo Graphics EXXR extra long range emitter ($780)

A Christie Mirage S+4K projector circa 2006, (1440 x 1050 resolution), no longer in production

An Nvidia Quadro P6000 graphics card ($3700)

with a stereo emitter bracket

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 _______________________________________________ Chimera-users mailing list: Chimera-users@cgl.ucsf.edu Manage subscription: http://plato.cgl.ucsf.edu/mailman/listinfo/chimera-users
