Sceneform SDK for Android was open sourced and archived (github.com/google-ar/sceneform-android-sdk) with version 1.16.0.
This site (developers.google.com/sceneform) serves as the documentation archive for the previous version, Sceneform SDK for Android 1.15.0.
Do not use version 1.17.0 of the Sceneform Maven artifacts.
The 1.17.1 Maven artifacts can be used. Other than the version, however, the 1.17.1 artifacts are identical to the 1.15.0 artifacts.

TransformableNode

AI-generated Key Takeaways

TransformableNode enables manipulation of nodes (translation, rotation, scaling) through gestures using the TransformationSystem.
It provides dedicated controllers for rotation (twist gesture), scaling (pinch gesture), and translation (drag gesture).
TransformableNode inherits functionalities from BaseTransformableNode for selection and transformation control, and from Node for general node manipulation like hierarchy, rendering, and event handling.
Developers can utilize the provided controllers and inherited methods to interact with and modify the node's properties within an AR scene.

public class TransformableNode
