# Cuboid Carousel

Rounded, bevelled cuboids carrying card content fly in from the right as one rigid group, cruise with a per-cuboid rotation stagger, decelerate to a hero hold, then exit left. Spacing is derived from the cuboid dimensions and the largest reachable X half-extent, so cuboids can never overlap. Forty variables carry the original DialKit schema: geometry, materials, lights, shadows, backdrop, camera and every segment duration and easing. Cards come from the built-in list or a JSON variable.

Composition id: `cuboid-carousel`. Duration 6.666666666666667 s at 30 fps, 1920×1080.

## Install

Install with `npx hyperframes add cuboid-carousel`; by default the files above land under `compositions/cuboid-carousel/`. Then mount the block from the host `index.html`:

```html
<div
  data-composition-id="cuboid-carousel"
  data-composition-src="compositions/cuboid-carousel/cuboid-carousel.html"
  data-start="0"
  data-duration="6.666666666666667"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>
```

Render with custom values by targeting the composition file directly:

```sh
npx --yes [email protected] render 'compositions/cuboid-carousel/cuboid-carousel.html' --variables '{"cardsJson":"","heroCard":4}'
```

## Variables

Read at runtime via `window.__hyperframes.getVariables()`; declared on the composition root as `data-composition-variables` (single-quoted attribute, plain JSON).

## Runtime contract

- One paused GSAP timeline registered as `window.__timelines["cuboid-carousel"]`.
- 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: WebGL, GSAP, Canvas 2D, PMREM, Shadow maps. Budget roughly 350 MB per live instance; run one at a time.
- External runtime dependencies: `./assets/three.module.min.js`, `./assets/addons/`.
- Web fonts from Google Fonts: Inter.

## 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.
