Thanks for the prompt response.
My responses are below.
I turned off depth cue and clipping with commands "light depthcue off" and "clip off" otherwise it clips to a slab which keeps moving as I move my head. I click a VR button on the ISOLDE panel tug atoms mouse mode icon to assign the VR button. I wouldn't say this makes ISOLDE usable in VR. For instance I don't have a way to move the roaming contour mesh region which normally stays in the middle of the screen. But it is enough to play around a bit. I was using a GTX 1080 Ti graphics card. Both the VR and ISOLDE molecular dynamics are running on the graphics card so this puts heavy demand on the card. For simulating just a region around a residue it was reasonably smooth.
Thanks for the tips to get it to work with ISOLDE. I have a 3090 to play with (which recently replaced my trusty 1080) that should have significantly better performance than the 1080 Ti. Let’s see how it goes…
I would like to make ISOLDE work well in VR. I think it is the perfect VR application where you really benefit from the best 3D perception possible and the 6-degree-of-freedom hand controllers for moving atoms around is much better suited than a mouse.
ABSOLUTELY, and I cannot wait for that day that I’ve been waiting for since I started working on structures, to come…
VR resolution has not been a major issue for use in molecular visualization. We have been using Vive Pro headsets that have adequate resolution for a few years now. A Valve Index headset is probably the best choice for molecular visualization right now. People also use Quest 2 with link cable.
I have an HP Reverb G2 that recently replated my original HTC Vive. I am quite disappointed with it so far, and was wondering whether I should’ve gone for an Index. However, Index is not sold in Australia (and therefore would have required having one shipped from the US, which means no warranty here and expensive shipping). That was one of the reasons for going for the G2, and I have already used that warranty, since the first unit they sent died after minutes of first use!
Do you think ChimeraX+ISOLDE should work with the WMR controllers that come with the G2, or is the current code specific to the Vive controllers?
The big problem is it would take many developer years of effort to have decent user interfaces in VR. The furthest along on this for molecular visualization is Nanome -- you should check out their molecular VR. We continued to develop ChimeraX VR including multi-person VR.
I have used Nanome’s one of the earliest versions, but it looks like they’re locking more and more of its features for free users based on my most recent try. ☹ Does it work as well as ChimeraX+ISOLDE in refining models?
Hello Tristan and the Chimera team,
I have been using ChimeraX in VR: fantastic!
However, ISOLDE was not working in VR, unfortunately.
Is there a fix/workaround currently available to get ISOLDE running in VR?
Is there ongoing work on making ISOLDE VR compatible?
Also: 1) are there any advantages of using a Quadro card over a consumer-line card for ChimeraX VR? and 2) is there a recommended minimum system spec for getting high-enough frame rates in VR with large models? We are planning to put together a new system soon for molecular visualization and modelling, hence the questions.
Now that there are VR headsets with high-enough resolution (such as the HP Reverb G2) that allow reading smaller text and finer details in VR, I am hoping that the molecular visualization and modelling software will start providing built-in easy-to-use support for these devices. I applaud ChimeraX team for leading in this space (no pun intended 😊).
