Hi Greg,

Thanks for you input. That does sound like using the ChimeraX VR support is the best and most optimal interface and way to go. I found this info:

‘VRto3D is a driver for SteamVR and SteamVR is a native OpenXR runtime. For SR displays, there's an additional step of installing reshade with 3D Game Bridge to SteamVR. Then any OpenXR game (I assume any application would work as well) will launch SteamVR and engage 3D. ‘

Sounds to me like this would be the way to go . Especially since it feel like that potential future developments and support on your site are more on the VR path.  

Maybe I’ll get a chance to test this and let you know. 

Best 
André

Hi Andre,

I have used this SBS mode with an older 3D projector, which flickers between each side coordinating with shutter glasses. It worked, and I don’t see why it wouldn’t work with the Samsung monitor as well. I think my comments on this from before were not stored in the thread, so here is a quick recap. 

Annoying things with this mode:

- the eye tracking is likely not communicated to ChimeraX, as it would be via openXR - whether this is possible who knows, Tom indicated it may not be, and without a monitor to try it out, likely would not be worked on
- so you have adjust the eye separation and distance to screen parameters yourself with ChimeraX commands to get a comfortable 3D effect - this will never be perfect, and your eyes will get tired quick; the new technologies that track your eyes make it a lot more comfortable
- as Tom said, Chimera does not go into real full screen mode, so there may be edge effects which make the mode not perfect
- the mouse cursor is only shown to one eye, so figuring out which side it’s on involves closing one eye
- the rotation is from the center of the screen, so you have to move the mouse there for rotating, rather unnatural
- selection happens on either left or right (with shutter glasses this seemed random), so a lot of times you’ll select the wrong thing, realize it, and move the mouse to the other side to select what you want, usually while closing one eye

All in all, I did use this mode for some time, and it’s still good to see things better in 3D. The other advantage of this mode is you could run it from Mac, Linux, or Windows, anything ChimeraX runs on. The openXR mode is only on windows right now.

Hi Tom and Greg,
Thanks so much for the infos.

I am torn between the 2 ‘normal’ displays from Samsung or Acer, which are also cheaper. Quite early I guess, but I notice some general excitement so future developments are not of the table i assume?

About the SBS: I noticed that it is a little complicated to get there, but it is possible to get ChimeraX into full screen, SBS on and all menus and bars including command prompt hidden. Isn’t this view a perfect SBS picture that the Samsung monitor should be able to use? Only question in this case would be if fullscreen mode is recognized as such by the monitor. If yes, shortcut to get there would be nice.

About the openXR:
I found the following about the Samsung monitor in a review online:
‘I want to take a moment to talk about XRGameBridge and VRto3D. This is a reshade plugin that you use to mod your Steam VR instance so that, along with VRto3D makes your SR display mimics a VR headset in a sense. With those tools alone you can launch steam VR games in 3D on your Spatial Reality (SR) display. What really excites me about this is that the developers managed to activate the monitors 3D mode without any special sdk from Samsung. I didn't realize this at the time but it seems like all SR displays  like Acer spatial labs and Lenovo Thinkvision 3D seem to use basically the same SR sdk, which may be made my Leia (makes of the lume pad and their own SR displays). This means that it might be possible for any developer to make some tools or apps to help round out this monitor’

Wouldn’t that be a possibility to get VR working?

A mode to just isolate the main window and drag it and full screen it to the 3D monitor would be helpful, but it sounded like hard to realize.

Thanks again 

Best
André

Hi Andre,

  We discussed the Samsung Odyssey 3D on the ChimeraX mailing list last month


The display manual does not mention OpenXR, only side-by-side stereo. 


Chimerax does not support fullscreen side-by-side stereo so it won't work with this display.  We might in the future add support.

Hi Andre,

I can pass some information since I’ve been looking into this with Tom Goddard a lot recently, not with the Samsung monitor, but with two others that have the same technology:

Tom has the ChimeraX latest builds working with the "Sony 3D Spatial Reality Display” monitors. You just have to connect the monitor, run ChimeraX and then type “xr on” in the command line.

We also tried the "Acer 3D SpatialLabs ViewPro 27”, but Tom found bugs in their openXR implementation, so the latest ChimeraX is not working with this yet, but likely there will be a fix very soon. Tom has a modified version of ChimeraX that works with this monitor, but it is not released yet.

You can google the above names, I would put links but they seem to vary by region. I am a huge fan of both of the above two monitors. The 3D effect is great, very useful for modeling and viewing complex models and 3D maps. Also super easy to run, compared to previous technologies. There are still some quirks, like that you have to interact with the 3D view on your main monitor, not on the 3D monitor directly.

There are no tests yet of ChimeraX with the Samsung monitor, that I know of. It looks really nice, but I didn’t find any info on whether it supports openXR or not, which is what ChimerX is using. We had some discussion on this list recently about whether it’s worth using the SBS mode, which it apparently supports, but that mode has even more quirks, so would not encourage.

Dear ChimeraX Team,

I was wondering if you had experience with the glasses-free Samsung Odyssey 3D monitor or know if ChimeraX is supporting it? Maybe you got already feedback from some users, as this seems like the perfect solution to work with!




Thank you 
Best, André
