Animation

SnapEngine animation wraps the Web Animations API so animations can participate in the engine frame loop. It supports ordinary CSS property animation and custom variables that can drive engine state.

Animations can be attached to objects and processed between render stages. This makes animation updates predictable relative to DOM writes, collision detection, and debug rendering.

Sequences group multiple animations behind one playback controller. They are useful when several elements or variables need to start, pause, reverse, or seek together.

For AnimationObject, SequenceObject, keyframes, custom variables, timing options, and playback controls, see Animation reference.
