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}'

Runtime contract

• One paused GSAP timeline registered as window.__timelines["glass-shard-title"].
• 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: 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)

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.
