NotifyingQuaternion class

Extension of the standard Quaternion class, implementing the ChangeNotifier functionality. This allows any interested party to be notified when the value of this quaternion changes.

This class can be used as a regular Quaternion class. However, if you do subscribe to notifications, don't forget to eventually unsubscribe in order to avoid resource leaks.

Direct modification of this quaternion's storage is not allowed.

Methods

absoluteError(Quaternion correct) → double

Absolute error between this and correct.

inherited

add(Quaternion arg) → void

Add arg to this.

override

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

asRotationMatrix() → Matrix3

Returns a rotation matrix containing the same rotation as this.

inherited

clone() → Quaternion

Returns a new copy of this.

inherited

conjugate() → void

Conjugate this.

override

conjugated() → Quaternion

Conjugated copy of this.

dispose() → void

Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).

inherited

inverse() → void

Invert this.

override

inverted() → Quaternion

Inverted copy of this.

inherited

normalize() → double

Normalize this.

override

normalized() → Quaternion

Normalized copy of this.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

relativeError(Quaternion correct) → double

Relative error between this and correct.

inherited

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

inherited

rotate(Vector3 v) → Vector3

Rotates v by this.

inherited

rotated(Vector3 v) → Vector3

Returns a copy of v rotated by quaternion.

inherited

scale(double scale) → void

Scales this by scale.

override

scaled(double scale) → Quaternion
