Kassadinsw/UnitySensorFusion

Sensor fusion for Unity (gyroscope and accelerometer) to get smooth orientation data from mobile devices without drift. Based on github.com/googlevr/webvr-polyfill

Usage:

• Add the component to the scene
• Call SensorFusion.Recenter() to "reset" the rotation
• Call SensorFusion.GetOrientation() to get the current rotation
