Re: [yt-users] yt-users Digest, Vol 111, Issue 44
Hi Matt,
Cheers for the info, I’ll take a look at your Unity code, I’m betting it’ll be better than my stab at it a few months back, I used someone else’s ray-marching code:
https://github.com/brianasu/unity-ray-marching/tree/volumetric-textures
Is it a mercurial repository? (I’ve just never used that before)
Hi Nathan,
My skillset doesn’t cover Open GL or general graphics either (yet, maybe in time), but I’m more than happy to help where I can and I have enough people here interested to get their data in VR that there’s a good amount of support. :)
I assume yt’s OpenGL volume rendering uses ray-marching?
Hi Suoqing,
Cheers, that’s cool, I’ll have to give that a try too, I’ll have to see if the data will look good on that.
Hi Jill,
That’s a good idea, I’d never heard of sketchfab, most of our datasets are more volume then surface, but it’s worth a try for some of my solar stuff.
Thanks guys, I’m getting loads of cool ideas from here.
Regards
Alex

Yup, we have been, and with the vive and oculus specifically. Right now though, it never got past much of a tech demo phase -- there's code on my group's bitbucket account (bitbucket.org/data-exp-lab/ ) that runs in Unity, and Nathan Goldbaum got some of the stuff that's in yt (the volume rendering) to work with the OpenVR python bindings directly (not srue where that code is) but it's all still pretty early on.
This code isn't really usable yet. In order for this to actually work, we'll need a big overhaul of the OpenGL volume rendering in yt to use multiple passes.
In addition there were significant performance issues that I never tracked down. Unfortunately I'm no expert on graphics programming and that's probably what's needed here.
Not sure it's quite shovel ready. There're some students coming on soon that will take another look, but July might be a bit optimistic... That being said, it'd be an awesome hack or collaboration and if you are interested in trying to push it at all, that'd be pretty rad.

I?ve managed to procure some VR headsets (HTC Vive, Oculus Rift and MS Hololens) and want to try and see if we could use them for visualising some of our simulation data. I hear you guys may have been playing with VR, is that true? Is there anything that we could use/play-with at this point?
Thanks

Hi All,
Just FYI - one can also generate points/surfaces with yt and upload them somewhere like Sketchfab and use their VR mechanisms.
Looking forward to what comes of it!
Cheers, -Jill
