orbit-card

# Orbit Card One centred feature card with a circular cut-out framing a dot sphere. The card enters from the right (0.25–1.80 s), holds with a subtle bob and depth drift, orbits a full turn around the sphere's centre (smoothstep between 4.97 and 5.97 s), and exits left (7.35–8.55 s). The camera path and card F-curves are exported from the approved Blender rig at 30 fps and interpolated; the sphere keeps its own translation and a constant spin. Title, description, accent and the orbit angle are variables; 180° and 720° work without touching keys. Composition id: `orbit-card`. Duration 10 s at 30 fps, 1920×1080. ## Files - `orbit-card.html` (3 KB) - `assets/Archivo-LICENSE.txt` (4 KB) - `assets/Three-LICENSE.txt` (1 KB) - `assets/archivo-regular.ttf` (108 KB) - `assets/archivo-semibold.ttf` (109 KB) - `assets/gsap-3.14.2.min.js` (128 KB) - `assets/GSAP-NOTICE.txt` (1 KB) - `assets/orbit-motion.js` (59 KB) - `assets/orbit-scene.js` (8 KB) - `assets/three.core.min.js` (554 KB) - `assets/three.module.min.js` (468 KB) ## Install Install with `npx hyperframes add orbit-card`; by default the files above land under `compositions/orbit-card/`. Then mount the block from the host `index.html`: ```html <div data-composition-id="orbit-card" data-composition-src="compositions/orbit-card/orbit-card.html" data-start="0" data-duration="10" data-track-index="1" data-width="1920" data-height="1080" ></div> ``` Render with custom values by targeting the composition file directly: ```sh npx --yes hyperframes@0.8.12 render 'compositions/orbit-card/orbit-card.html' --variables '{"feature1Title":"Always in sync","feature1Desc":"Changes reach every screen the moment they happen."}' ``` ## Variables Read at runtime via `window.__hyperframes.getVariables()`; declared on the composition root as `data-composition-variables` (single-quoted attribute, plain JSON). | id | type | default | label / range | | ------------------ | ------ | ------------------------------------------------------ | -------------------------------------- | | `feature1Title` | string | `"Always in sync"` | Card title max 28 chars | | `feature1Desc` | string | `"Changes reach every screen the moment they happen."` | Card description max 110 chars | | `feature1Accent` | color | `"#4cc9ff"` | Card accent | | `cardOrbitDegrees` | number | `360` | Card orbit degrees -36000–36000 step 1 | ## Runtime contract - One paused GSAP timeline registered as `window.__timelines["orbit-card"]`. - Re-syncs on the `hf-seek` CustomEvent; every frame is a closed-form function of time (seeded PRNG only, no rAF loops, no Date.now). - Renderer: GSAP. - External runtime dependencies: none (served locally). - Local fonts: assets/archivo-regular.ttf, assets/archivo-semibold.ttf. ## Editing rules (from the source project) 1. Keep `data-composition-variables` a single-quoted attribute with plain `"` JSON. Never save it through Studio's Design panel. 2. Do not put `<canvas>` in static markup; create it at runtime. 3. Keep every visual state a function of t; seek-safety is what makes the block renderable.
