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.

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:

<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:

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.
