Also,

Tried XR on. The display froze but did go into the 3D mode. Chimerax is recognizing the driver and the monitor. I got an error while reporting this bug. So pasting it here.

 

 

An error occurred in drawing the scene. Redrawing graphics is now stopped to avoid a continuous stream of error messages. To restart graphics use the command "graphics restart" after changing the settings that caused the error.

Hi Krish,

 

  I would hope the Acer SpatialLabs 3D display could render with the standard sequential stereo used with old LCD shutter glasses or polarized glasses systems.  ChimeraX can output that using command "camera stereo".  But I didn't seen any indication in searching online that they support that.  Nor did I see any mention of them supporting the standard side-by-side stereo format which ChimeraX can also output (camera sbs).  I would think the display would handle these format because 3D games use those.  How could they not make it work with 3D games?  What I did see online is that it works with OpenXR which is what virtual reality headsets use.  That makes sense because the display offers eye tracking and the sequential or side-by-side stereo methods would not be able to use the eye tracking to change the viewing angle as you moved your head, while software that uses OpenXR will allow that.  ChimeraX can uses OpenXR, command "xr on".  I did not see online what software you use with the display to work with OpenXR.   It would need some SpatialLabs OpenXR display control software running on your computer.  Here is a bit of discussion about trying to use this display with another 3D app called Slicer

 

https://link.edgepilot.com/s/cad1c1c9/DC6RKYZmHE2WohxUaEbXfw?u=https://discourse.slicer.org/t/spatiallabs-stereoscopic-display/34800

 

where the poster did get Slicer's OpenXR to show 3D with the display.

 

  Let me know what you figure out.  If you find some technical reference for the display online that explains the types of 3D input it accepts or how to set it up to work with applications that use OpenXR, I'd be interested in seeing that documentation.  If it works well my lab might get a display.

Hi Tom,

I got a new 3d glasses free monitor.

I used the spatiallabs  (GO app) software to see stereoscopic 3d images from Chimerax, coot(mapfitting) amd MOE. Seemd to work fine.

The Go app converts any 2d to 3d stereo when the program displaying is set to fullscreen.

The Spatiallabs software from acer has plugins for unity , blender and  a few other software suites.

The Go app is compatible with *.obj and Gitf 3d formats. I tried those from chimerax and the result is spectacular.

Is there any possibility of getting a chimerax plugin?

Regards

Krish

Hi Krishnan, 

 

  We do not have any of the new 3D laptops to try ChimeraX.  Let us know if it works.  You will probably use the ChimeraX command "camera stereo" to put it into 3D model on one of these 3D laptops.

 

  Samsung also showed a 3D monitor at January's Consumer Electronics Show with rumors that it may come out this summer.  Also don't know if ChimeraX will work on that display.

 

  While I think ChimeraX stereo is likely to work on these displays a problem with past stereo that used shutter glasses was that only workstation graphics cards could do stereo in a window, meaning that part of the display is showing 3D (e.g. the ChimeraX graphics pane) while the rest is showing 2D.  This required special graphics driver support only offered in the workstation cards (like Nvidia Quadro) and not in the consumer cards.  Full screen stereo where everything is rendered in 3D was available on consumer cards mostly for video games where everything is in 3D including user interface elements.

 

  Let us know if you get something working.

 

Tom

maybe we can see chimerax😊 in 3d in these… they do have a plugin for unity.. Iam trying get one of these to try things out.
