DeviceOrientationCamera initial rotation

[onurhanaytac]

Hello everyone,

I want to set my DeviceOrientationCamera initial rotation. I dig forum and found something about resetToCurrentRotation() but im not able to make it work. I want my DeviceOrientationCamera start with looking a target like ArcRotateCam What i mean by this I place my cam to right place but it look to wrong direction for initial position.

 

cam = new babylon.DeviceOrientationCamera("DeviceOrientationCamera", position, scene);
cam.rotationQuaternion.y = Math.PI / 2;
cam.resetToCurrentRotation();

 

For example i want to turn my DeviceOrientationCamera X degree in Y axis then start controlling with device. What should i do?

Thanks in advence!

Hello you are doing it correctly except for the rotationQuaternion. If is not angles for rotation but a quaternion

you can affect it like this: cam.rotationQuaternion = BABYLON.FromRotationMatrix(BABYLON.Matrix.RotationY(Math.PI / 2));

Thanks for the answer @Deltakosh 

self.cam.rotationQuaternion = babylon.Quaternion.FromRotationMatrix(babylon.Matrix.RotationY(self.toRadians(self.compassDegree)));

I did fix the angle. My scene know shows up correctly but after a second cam turns the same position i think i am not able to reset the rotationQuaternion

https://www.babylonjs-playground.com/#8FFPCG#4 here is a code similar to what im doing.

when i open this with my phone i need to turn the device X degree to see the scene. But just for a sec in the beginning it is rotate the cam i think I cannot reset the cam at that moment.

Perhaps try to do it in the scene.registerBeforeRender ?
