Add Oculus support

[dmarcos]

I also tried Oculus over Steam VR. Running exokit.sh -h and pressing ctrl-1 to enter VR mode results in a crash.

[avaer]

Are you able to post the log when you perform the above steps? (console output of the command)

Steam VR is the one that theoretically should work.

[dmarcos]

This is the error I get when launching node index.js -h after pressing ctrl-1 and Oculus Rift present via SteamVR.

Thanks, this looks like the format of the texture is one oculus binding doesn't like. Needs some research.

[avaer]

Would be curious if the OpenVR example works in Oculus SteamVR, because that's pretty much what Exokit is doing.

[avaer]

Work on this issue might have conflicts with #286.

[dmarcos]

Thanks for letting me know. I'm planning to get back to this after next week.

[etiennepinchon]

Same issue.

[shawwn]

I’m getting this too.

[avaer]

@dmarcos Is there a starting base for Oculus/libOVR bindings? I think @cmdrflexo wanted to dive in.

[ngokevin]

Not sure if he had too much, at least not NAN bindings. I think flexo could start. I was gonna start on the mobile SDK.

Just to throw in my two cents here, I have been able to use it on oculus through steam many times.

I usually start like this in the exokit folder:

Exokit version 0.0.482 - installed via git clone and npm install.

node . https://aframe.io/a-painter/

[avaer]

Is there any performance hit or gotchas when doing so? I'm glad it works either way, was a pleasant surprise to hear.

[sidequestlegend]

Not that i'm aware of, it just works. I actually used it quite a while ago around version 0.0.420 😏 and it worked just as well. Only issue i have was the movement-controls component had its axis' reversed but i don't think that was anything to do with exokit as it was already reported on their issue tracker.

Maybe we should all list the kit we have in a sticky location so we know what everyone has to test with.

[ngokevin]

Cool! Still will want native support, especially as headsets go standalone. I think there'd be some perf issues (we saw on WMR + Steam), perhaps as the app scales. Like does ATW work?

[avaer]

Agree, should aim for native on all desired platforms. I'm guessing there's no other option for Santa Cruz/Quest anyway.

Quest is Android though, so I'm not sure how much the binding would be Android vs how much OVR.

[sidequestlegend]

I'm not sure on the ATW, how do i check that?

[ZNixian]

Hi, I'm planning to start work on adding a native LibOVR binding. Just checking if anyone else has started work on this?

[avaer]

Would be much appreciated!

I don't think @dmarcos got very far, though there is a binary module at https://www.npmjs.com/package/native-oculus-deps

[avaer]

@dmarcos related to this, would you mind sharing collaborator status on npm/native-oculus-deps with @kazmer?

[dmarcos]

Done

[avaer]

Thanks!
