Measure angles between two points on the geo sphere with the camera and augmented reality.

Device orientation is obtained with the accelerometer and gyroscope or with the accelerometer and magnetic field sensor. Each method has advantages and disadvantages and can be selected with the gyro or magnet buttons (only if your device has the necessary sensors detected).

A sphere with azimuth and angle of elevation lines is shown overlaying the camera view.
Two positions can be set putting markers onto the view. The angle required to rotate from one to the other is shown as is the difference in azimuth and angle of elevation between the two points.

For Indication Only. Note that in gyroscope mode the azimuth will drift slowly. In magnetic mode the Earths magnetic field can be distorted by nearby metallic objects and give incorrect azimuth readings. For Indication Only.
