This is a rough sketch of how Chrome plans to deliver Animation Worklet features:
- Animation Worktlet Prototype (done): scripted custom animation, single effect, only fast properties, off-thread.
- Animation Worktlet Origin Trial (in progress, signup): good performance, scroll input (ScrollTimeline), basic web-animation controls (play/cancel).
- Animation Worktlet MVP (in development): animate all properties (slow path ones running in sync with main thread), multiple effects (i.e., GroupEffect), full web-animation integration.
- Animation Worktlet V2 (future): touch/gesture input, multiple inputs in single animation, sophisticated scheduling, other outputs.
