Titanium Mobile # CoreMotionAttitude
The attitude of the device.
3.3.0NOTE
This is an abstract type. Any object of this structure can be used where this type is used.
# Properties
# pitch READONLY
3.3.0The pitch of the device, in radians.
A pitch is a rotation around a lateral axis that passes through the device from side to side.
# quaternion READONLY
3.3.0Returns a quaternion representing the device's attitude.
See CoreMotionQuaternion for further information.
# roll READONLY
3.3.0The roll of the device, in radians.
A roll is a rotation around a longitudinal axis that passes through the device from its top to bottom.
# rotationMatrix READONLY
3.3.0Returns a rotation matrix representing the device's attitude.
A rotation matrix in linear algebra describes the rotation of a body in three-dimensional Euclidean space.
# yaw READONLY
3.3.0The yaw of the device, in radians.
A yaw is a rotation around an axis that runs vertically through the device. It is perpendicular to the body of the device, with its origin at the center of gravity and directed toward the bottom of the device.
# Methods
# multiplyByInverseOfAttitude
3.3.0Yields the change in attitude given a specific attitude.
This method multiplies the inverse of the specified CoreMotionAttitude object by the attitude represented by the receiving object. It replaces the receiving instance with the attitude change relative to the object passed in attitude. You should cache the CoreMotionAttitude instance you want to use as a reference and pass that object as the argument to subsequent calls of this method.
