v 1.0.4 (master) no world position of the camera with Oculus Quest

[smeybi]

With the Oculus Quest you can get the world position of the camera (0 0 0). Only the camera has this issue, all other works. Only with the Oculus Quest, it works with the HTC Vive, you can get the camera world position.

el.object3D.getWorldPosition()

I'm not sure it's right place here to report this issue instead of three.js

• A-Frame Version: 1.0.4 + (master)
• Platform / Device: Oculus Browser / Oculus Quest
• Reproducible Code Snippet or URL:

Here is a demo, the entity in the camera get the world position, not the camera itself.

I have the same issue. Also there is workaround: cameraEl.object3D.matrixAutoUpdate = true; or use cameraEl.components["camera"].camera.getWorldPosition()

getWorldPosition doesn’t work in VR mode. It’s a known THREE bug See this commit for alternative

var originVec3 = new THREE.Vector3();
el.object3D.updateMatrixWorld();
originVec3.setFromMatrixPosition(el.object3D.matrixWorld);

Ah ok, I hadn't seen it, thanks!
