Glass Shard Title
Voronoi-cut glass panes fly in from depth, rotating, and land as a tiled silhouette of the headline, then fly out past the camera. Each shard is a Sutherland–Hodgman clip of a jittered blob against its Voronoi cell, so the pieces always cover the type. Glass and matcap surfaces get per-fragment fog; the z-flight is decoupled from the ease so shards visibly traverse it. Tile count 1 gives a single pane.
Composition id: glass-shard-title. Duration 12.16 s at 30 fps, 1920×1080.

Install
Install with npx hyperframes add glass-shard-title; by default the files above land under compositions/glass-shard-title/. Then mount the block from the host index.html:
<div
data-composition-id="glass-shard-title"
data-composition-src="compositions/glass-shard-title/glass-shard-title.html"
data-start="0"
data-duration="12.16"
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/glass-shard-title/glass-shard-title.html' --variables '{"headline":"Designed in glass","tileCount":8}'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["glass-shard-title"]. - Re-syncs on the
hf-seekCustomEvent; every frame is a closed-form function of time (seeded PRNG only, no rAF loops, no Date.now). - Renderer: three.js 0.181.2 (bundled), GSAP 3.14.2, Canvas 2D, GLSL shaders, HDR environment, Matcap, Seeded PRNG, d3-delaunay, Shadow maps. Budget roughly 350 MB per live instance; run one at a time.
- External runtime dependencies:
https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js,https://cdn.jsdelivr.net/npm/d3-delaunay@6.0.4/dist/d3-delaunay.min.js. - Local fonts: assets/fonts/Geist-Regular.ttf, assets/fonts/Geist-SemiBold.ttf, assets/fonts/Geist-Bold.ttf.
- Bundled code is inlined into the composition (assets/glass-main.js); rebuild with esbuild and re-inline after editing the .mjs source.
Editing rules (from the source project)
- Keep
data-composition-variablesa single-quoted attribute with plain"JSON. Never save it through Studio's Design panel. - Do not put
<canvas>in static markup; create it at runtime. - Keep every visual state a function of t; seek-safety is what makes the block renderable.
