SceneView.AnimationTimeTransformer

  • SceneView.AnimationTimeTransformer is an interface in ARCore's Sceneform used to control the timing of animations within a SceneView.

  • It provides a method, getAnimationTime, which converts the Choreographer's frame time into the desired animation time, enabling custom animation playback speeds and behaviors.

  • By implementing this interface, developers can manipulate the animation timeline, allowing effects like slow motion, fast forward, or even pausing and resuming animations.
