googlevr/vrview Read position form onGetPosition and set its value for next init

Question

I'm wondering if it is possible (I hope it is) to set init camera rotation read from onGetPosition?

My onGetPosition function look like this:

function onGetPosition() {
    console.log({
        Yaw: worldRenderer.camera.rotation.y * 180 / Math.PI,
        Pitch: worldRenderer.camera.rotation.x * 180 / Math.PI,
        x: worldRenderer.camera.rotation.x,
        y: worldRenderer.camera.rotation.y,
        z: worldRenderer.camera.rotation.z
    });
...
}

I use this image as a texture:

Initial view, with default_yaw set to 0 degrees looks like this: In this position onGetPosition returns: {Yaw: 0, Pitch: -0, x: -0, y: 0, z: -0}

Then I rotate the scene to see this position (about 90 deg to the left): onGetPosition returns: {Yaw: 75.66036892219512, Pitch: -42.97581864568984, x: -0.7500695341072581, y: 1.3205225509658982, z: 0.7343037709331535}

I thought that if I set camera rotation inside setDefaultYaw_ function I would see last view so I did this:

WorldRenderer.prototype.setDefaultYaw_ = function(angleRad) {
    ...
    this.camera.setRotationFromEuler(new THREE.Euler(-0.7500695341072581, 1.3205225509658982, 0.7343037709331535, 'XYZ'));
};

Unfortunately nothing happened I still see the view from second image on init. How can I solve it?
