Three.js and WebGL adapter patterns for HyperFrames. Use when creating deterministic Three.js scenes, WebGL canvas layers, AnimationMixer timelines, camera motion, shader-driven visuals, or canvas renders that respond to HyperFrames hf-seek events.

We split this skill into the rules it gives an agent

4 rules. 1 is common, 0 are distinctive, and 3 are very specific to this project.

  • 1

    Common

    Most of the 7 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 3

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Common:

    Create the scene, camera, renderer, materials, and assets synchronously when possible.

    line 13
  2. Very specific:

    Avoid requestAnimationFrame or renderer.setAnimationLoop as the source of truth for render-critical motion.

    line 17
  3. Very specific:

    If several mixers exist, seek all of them from the same time.

    line 78
  4. Very specific:

    After editing a Three.js composition:

    line 96

“Common” is measured: kept by at least 6 in 10 of the 7 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Three.js for HyperFrames

HyperFrames supports Three.js through its three runtime adapter. The adapter does not own your scene. It publishes HyperFrames time and dispatches a seek event so your composition can render the exact frame.

Contract

  • Create the scene, camera, renderer, materials, and assets synchronously when possible.
  • Render from HyperFrames time, not wall-clock time.
  • Listen for the hf-seek event and render exactly that time.
  • Load models, textures, and HDRIs before render-critical seeking. Do not fetch them at seek time.
  • Avoid requestAnimationFrame or renderer.setAnimationLoop as the source of truth for render-critical motion.

The adapter sets window.__hfThreeTime and dispatches new CustomEvent("hf-seek", { detail: { time } }) on each seek.

Basic Pattern

<canvas id="three-layer"></canvas>
<script type="module">
  import * as THREE from "https://cdn.jsdelivr.net/npm/three@0.181.2/+esm";

  const canvas = document.getElementById("three-layer");
  const renderer = new THREE.WebGLRenderer({ canvas, alpha: true, antialias: true });
  // Match these to your composition's frame size.
  renderer.setSize(1920, 1080, false);
  renderer.setPixelRatio(1);

  const scene = new THREE.Scene();
  const camera = new THREE.PerspectiveCamera(35, 1920 / 1080, 0.1, 100);
  camera.position.set(0, 0, 6);

  const mesh = new THREE.Mesh(
    new THREE.IcosahedronGeometry(1.4, 4),
    new THREE.MeshStandardMaterial({ color: 0x64d2ff, roughness: 0.38 }),
  );
  scene.add(mesh);
  scene.add(new THREE.HemisphereLight(0xffffff, 0x223344, 2));

  function renderAt(time) {
    mesh.rotation.y = time * 0.7;
    mesh.rotation.x = Math.sin(time * 0.6) * 0.16;
    renderer.render(scene, camera);
  }

  window.addEventListener("hf-seek", (event) => {
    renderAt(event.detail.time);
  });

  renderAt(window.__hfThreeTime || 0);
</script>
#three-layer {
  width: 100%;
  height: 100%;
  display: block;
}

AnimationMixer Pattern

For GLTF or authored clip animation, seek the mixer directly:

function renderAt(time) {
  mixer.setTime(time);
  renderer.render(scene, camera);
}

If several mixers exist, seek all of them from the same time.

Good Uses

  • Deterministic 3D objects, product spins, particles with seeded data, and shader plates.
  • Camera moves derived from time.
  • GLTF animation clips when assets are local and loaded before validation completes.

Avoid

  • Using Date.now(), performance.now(), or clock deltas to update scene state.
  • Leaving render-critical work inside a free-running animation loop.
  • Loading remote models or textures at render time.
  • Device-pixel-ratio dependent output. Pin renderer size and pixel ratio for video renders.
  • Post-processing passes that depend on previous frame history unless you can reconstruct state from time.

Validation

After editing a Three.js composition:

npx hyperframes lint
npx hyperframes validate

    How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

      contribute-catalog

      Author a new HyperFrames registry block (caption style, VFX block, transition, lower third) or component (text effect, overlay, snippet) and ship it as an upstream PR to the hyperframes repo. Use ONLY when the user wants to CONTRIBUTE to the public catalog — for in-project caption/transition authoring use the `hyperframes` skill, for installing existing registry items use the `hyperframes-registry` skill.

      typegpu

      TypeGPU is type-safe WebGPU in TypeScript. Use whenever the user writes, debugs, or designs TypeGPU code: 'use gpu' shader functions, tgpu.fn, buffers, textures, bind groups, compute and render pipelines, command encoders, render passes, render bundles, vertex layouts, slots, accessors, @typegpu/react hooks (useRoot, useFrame, useUniform), React Native worklet rendering, and any TypeGPU API. Shader logic and CPU-side resources are tightly coupled - handle both sides here even if the user only mentions one (e.g. "how do I write a shader", "how do I create a buffer"). Trigger on any mention of typegpu, tgpu, "use gpu", TypedGPU, or WebGPU code written using TypeGPU's schema API (d.*, tgpu.*, std.*). Do NOT trigger for raw WebGPU (using GPUDevice/GPURenderPipeline directly without tgpu), WGSL-only questions, Three.js, Babylon.js, or WebGL.

      impeccable

      Use when the user wants to design, redesign, shape, critique, audit, polish, simplify, harden, animate, or otherwise improve a frontend interface: websites, landing pages, dashboards, product UI, components, forms, settings, onboarding, empty states, and native iOS or Android screens. Handles UX review, hierarchy, layout, typography, color, motion, UX copy, accessibility, responsive behavior, edge cases, and capturing or documenting design systems (DESIGN.md, tokens). Also for making bland UI bolder, loud UI quieter, or ambitious visual effects. Not for backend-only or non-UI tasks.
