TranslationController

Page Summary

The TranslationController class manages the movement of a BaseTransformableNode within an AR scene using drag gestures.
It selects the BaseTransformableNode when a drag gesture begins if it's not already selected and then manipulates its position.
Developers can control the allowed plane types for translation using getAllowedPlaneTypes and setAllowedPlaneTypes methods.
It provides methods like canStartTransformation , onContinueTransformation , and onEndTransformation to manage the transformation lifecycle.
isTransforming indicates the current transformation state of the controlled node.

public class TranslationController

Manipulates the position of a BaseTransformableNode using a DragGestureRecognizer . If not selected, the BaseTransformableNode will become selected when the DragGesture starts.
