Keyframe Patterns

const root = document.querySelector("[data-composition-id]");
const id = root.dataset.compositionId;
const tl = gsap.timeline({ paused: true });
tl.to("<selector>", {
  keyframes: [
    /* derive poses from the scene */
  ],
  ease: "none",
});
window.__timelines = window.__timelines || {};
window.__timelines[id] = tl;

.<subject > {
  animation: <name> <duration> <ease> both;
  animation-iteration-count: 1;
}
@keyframes <name> {
  0% {
    transform: <pose-a>;
    opacity: <a>;
  }
  100% {
    transform: <pose-b>;
    opacity: <b>;
  }
}

const animation = anime.createTimeline({ autoplay: false });
animation.add("<selector>", {
  /* derived channels */
});
window.__hfAnime = window.__hfAnime || [];
window.__hfAnime.push(animation);

const state = { progress: 0 };
tl.to(state, {
  progress: 1,
  duration: <duration>,
  onUpdate: () => {
    // derive camera/object/material values from state.progress
    renderer.render(scene, camera);
  },
});
