Hi everyone, I would like to get the real world rotation of a device, but I don't clearly know how to achieve that. I'm trying to use the gyroscope attitude function, but it doesn't work for me. I only want the x and y rotation (in Euler angles) values, so if I move the head in a horizontal way, the y rotation angle is moving, and if I move the head verticaly, the x rotation angle moves. The z angle doesn't really matter, it will always be 0. But I want it to be in the real world rotation, so I mean that when I start on the app and I'm looking 90 degrees away from the north, that it is shown in the rotation values.. Anyone got a clue how to achieve that?
