Janus VR: double vision

[roothorick]

Janus VR runs and successfully submits textures to the compositor, but there's a double vision effect in the headset, as if the eye textures are swapped.

You might not need it soon.
I poked Aussie from the JanusVR crew about my vive now working pretty well in linux and what happened when trying to run it.
He'll probably get back to me with some info about it later.

Janus is nonetheless important for WOVR because it's known to use OpenGL on Windows and doesn't have unrelated hangups preventing it from running. We have precious few options for testing non-D3D support.

I need to test with a more recent SteamVR however. I had it working without the double vision issue some time ago, but the system was unstable due to a driver bug. I'm now working with newer NV drivers and SteamVR seems to be more stable. It may have been a SteamVR bug all along, but I need to confirm that.

hehe, okay.
Sorry, I've been using janus since the end of 2014 and have been following the changes there.
I was messing with it when it still was called FireBox 😄
So, with this library, you can to some extent run windows vr apps/games ?

The end goal is WineOpenVR will enable VR apps to work just as well in Wine as they would as normal desktop apps i.e. 80%+ of apps will work, and those that don't work, don't work due to shortcomings in Wine itself (and I suspect 95%+ of those will be in d3d11).

Obviously, D3D not working is the one big showstopping hurdle for that goal, so I've been singularly focused on that. I definitely could use help -- patches to Wine itself implementing certain functionality is required, and my working knowledge on virtually everything involved there is minimal.

Right now, in theory, OpenGL and Vulkan apps should be up and fully running, and if they're not, I very very much so want to hear about it. Problem is, OpenGL and Vulkan VR apps are very few and far between. D3D, as per the above, don't bother asking, I already know.

Interesting, never thought to use Janus in Wine. Their current release almost works in Linux naively but has some dependency problems for anything but Ubuntu. Dev(s) didn't seem to care.

you could create a ubuntu chroot and run it from there.
And I can attest to janusvr working with the vive on ubuntu 17.10
