[SOLVED] WebVR Polyfill error after Update

Help & Support
1

Following the issue of the WebXR update - error, which might be related:
I still get this error for my webVR Project after the last update. I use the WebVRPolyfill for all mobile devices (including android).
It might be a specific project / rendering configuration, as I had issues with native xr as well (which led me to switching entirely to the polyfill). It’s a rather large project, but I could make it temporarely public if it could help.

playcanvas-stable.dbg.js:15416 Uncaught TypeError: viewMat3L.setFromMat4 is not a function
    at ForwardRenderer.setCamera (playcanvas-stable.dbg.js:15416)

Can you reproduce this on PC/Mac as well? If yes, please add me to your project, I’ll have a quick look if that’s ok. My user name: mvaligursky

Ok - I’ve created now a completely reduced scene - only including the basic vr-setup.
I’ve also integrated the current version of the webVR Polyfill (as I did some minor modifications there within my project).

See the public project:
https://playcanvas.com/editor/project/755352
and build:

Currently I use the webVR Polyfill also on android, using this at vr.js | line 96

if (this.app.xr.isAvailable(pc.XRTYPE_VR) && false) {

This results in the errors, I mentioned above.

If I use webXR native on my Samsung S10 I get following error, after the view changes to stereo mode: The website is not responding.

Any help would be very appreciated.

I’m a bit confused. Why are you using the WebVR polyfill with a WebXR application?

5

The problem was that on my S10 the native xr version didn’t work, like I mentioned before this resulted in a freeze “website is not responding”
Therefore I routed all my webVR stuff over the webVRPolyfill, also to have a consistent experience for iOs and Android (showing the cardboard-info there as well)

What was wrong with the WebXR polyfill?

7

Just to be clear, WebVR and WebXR are two separate APIs and AFAIK, not compatible with each other.

You are right. If I can manage to get the WebVR Polyfill running again, I will stick with WebVR and the WebVR Polyfill. After the core errors I got today I thought I would had to switch to WebXR and the WebXR Polyfill.
The problem with the WebXR Polyfill is, that I haven’t managed to “force” it’s use also on android, which was very simple with the WebVR Polyfill.
With WebXR I also have rewrite & test some parts, like the VR Magic Window mode from my other post.

Do you have any WebVR projects / starter templates, which are still working with the WebVR Polyfill? I’m just wondering as none of my WebVR projects seem to be working.

I haven’t checked this recently, but I restored the old WebVR starter kit just in case last year when we did the switch to WebXR.

Thank you very much. I’ve checked it on my phone, and I get the same errors:

‘Uncaught TypeError: viewMat3L.setFromMat4 is not a function
at ForwardRenderer.setCamera (playcanvas-stable.dbg.js:15416)
at ForwardRenderer.renderComposition (playcanvas-stable.dbg.js:17506)
at Application.render (playcanvas-stable.dbg.js:62033)
at playcanvas-stable.dbg.js:62735’

I think the WebXR Polyfill is now the only way to go. But thanks again for your time.

That’s starting to look like a bug in our engine. I or Martin (@mvaligursky) will take a look as soon as we can.

Thank you very much. If I can provide any help (testing on different devices or else), just let me know.

Ah yeah. viewMat3L is a Mat4, not a Mat3. Whoops. :smile:

Thanks for the quick fix, I will check with the older version of my project (as I’m currently updating everything to the webXR api), but I think that should solve it. Thanks.
