[chimerax-users] [Chimera-users] Stereo glasses

[Greg Couch]

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

>>>    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).

>>> 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.
