Resetting device rotation


Recommended Posts

Using camera.resetToCurrentRotation() I am able to set my camera to point to z+.

I really need to set the camera rotation on the y axis to face z- or x+ or x- as well.

Unfortunately I have been blundering about with quaternions for 2 days, and I can't seem to make it do what I want. Or it will do what I want, but only when the device is pointing a specific direction(very odd).

I gave up on Quaternions. Solved my problem with Euler instead.

cam._initialQuaternion.x = 0;
cam._initialQuaternion.z = 0;
cam._initialQuaternion.y *= -1;
var rot = cam._initialQuaternion.toEulerAngles()
rot.y += Number(180).toRadians();
BABYLON.Quaternion.RotationYawPitchRollToRef(rot.y,rot.x,rot.z, cam._initialQuaternion);
// Apply to camera
cam._initialQuaternion.multiplyToRef(cam.rotationQuaternion, cam.rotationQuaternion);
