Page Summary
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.
public static interface
SceneView.AnimationTimeTransformer
Defines a transform from Choreographer time to animation time. Used to control the
playback of animations in a SceneView.
Transforms nanosecond times generated from the Choreographer to generate the
animation update time.
Public Methods

long
getAnimationTime(long choreographerTime)
Transforms nanosecond times generated from the Choreographer to generate the
animation update time. The input nano time can be used to ensure that returned times never
decrease.
Parameters
choreographerTime
the current frame time returned from the Choreographer.

The core action is performed by the `getAnimationTime(long choreographerTime)` method. This method takes the current frame time from the `Choreographer` as input and returns the corresponding animation update time. This allows for control over animation time based on nanosecond time input from the `Choreographer`, ensuring that time values are non decreasing.\n"]]
