AI-generated Key Takeaways
BaseGestureRecognizer.OnGestureStartedListener is an interface used to define callbacks triggered when a BaseGesture starts.
This interface includes a single method, onGestureStarted(), which is invoked with the specific gesture instance that began.
Several classes, including DragGestureRecognizer, PinchGestureRecognizer, and TwistGestureRecognizer, utilize this interface for gesture detection.
Controllers like RotationController, ScaleController, and TranslationController indirectly rely on this interface via their interactions with these gesture recognizers.
These components work together within Sceneform to enable user interaction and manipulation of 3D objects in augmented reality environments.

Several subclasses implement this, including `DragGestureRecognizer`, `PinchGestureRecognizer`, and `TwistGestureRecognizer`, each handling specific gesture types. Controllers like `RotationController`, `ScaleController`, and `TranslationController` utilize these recognizers to manipulate node properties. The `onGestureStarted` method, when called, receives a generic gesture object. The main actions are to trigger and recognize when a gesture starts.\n"]]
