Package pro.streem.ar.sceneform.ux

Class ScaleController

java.lang.Object

pro.streem.ar.sceneform.ux.BaseTransformationController<PinchGesture>

pro.streem.ar.sceneform.ux.ScaleController

All Implemented Interfaces:

pro.streem.ar.sceneform.Node.LifecycleListener, BaseGesture.OnGestureEventListener<PinchGesture>, BaseGestureRecognizer.OnGestureStartedListener<PinchGesture>

public class ScaleController
extends BaseTransformationController<PinchGesture>

Manipulates the Scale of a BaseTransformableNode using a Pinch PinchGestureRecognizer. Applies a tunable elastic bounce-back when scaling the BaseTransformableNode beyond the min/max scale.
