PinchGestureRecognizer

  • PinchGestureRecognizer detects two-finger pinch motions on a touchscreen for use in AR interactions.

  • It provides a listener, OnGestureStartedListener, to react when a pinch gesture begins.

  • The tryCreateGestures method is used internally to handle touch events and identify potential pinch gestures.

  • This class inherits functionalities from BaseGestureRecognizer for managing gestures.

  • You can use this class to implement interactive scaling or zooming functionalities in your AR applications by responding to the pinch events.
