- 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.
SceneView.AnimationTimeTransformer

Defines a transform from Choreographer time to animation time. Used to control the
playback of animations in a SceneView.

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"]]
