Canopy Part Title

A dense canopy of textured leaves sweeps across the frame with shallow depth of field, then parts to uncover the first headline; a second, depth-lifted batch carries the second headline past the camera. A handful of leaves stay behind on the type and keep a light breeze. Font, weight, size, letter spacing, leaf counts, sweep speed and the retained-leaf breeze are variables.

Composition id: canopy-part-title. Duration 12 s at 30 fps, 1920×1080.

Install

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

<div
  data-composition-id="canopy-part-title"
  data-composition-src="compositions/canopy-part-title/canopy-part-title.html"
  data-start="0"
  data-duration="12"
  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/canopy-part-title/canopy-part-title.html' --variables '{"headline1":"Understory","headline2":"Move slowly"}'

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
`headline1`	string	`"Understory"`	Headline 1
`headline2`	string	`"Move slowly"`	Headline 2
`font`	string	`"Helvetica"`	Headline font
`fontWeight`	number	`900`	Font weight 100–900 step 100
`fontSize`	number	`1`	Font size (1 = auto-fit) 0.3–2 step 0.01
`letterSpacing`	number	`0.01`	Letter spacing (em) -0.2–1 step 0.01
`background`	color	`"#020805"`	Background
`leafCount`	number	`170`	Leaves per sweep 40–320 step 1
`stayCount`	number	`5`	Leaves left behind 0–20 step 1
`sweepSpeed`	number	`1`	Sweep speed 0.3–3 step 0.05
`retainedBreeze`	number	`1`	Retained leaf breeze 0–2 step 0.05

Runtime contract

One paused GSAP timeline registered as window.__timelines["canopy-part-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 0.170.0, GSAP 3.14.2, Canvas 2D, Post-processing, Seeded PRNG, 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/three@0.170.0/build/three.module.js, https://cdn.jsdelivr.net/npm/three@0.170.0/examples/jsm/postprocessing/EffectComposer.js, https://cdn.jsdelivr.net/npm/three@0.170.0/examples/jsm/postprocessing/RenderPass.js, https://cdn.jsdelivr.net/npm/three@0.170.0/examples/jsm/postprocessing/BokehPass.js.
Web fonts from Google Fonts: Gelasio.

Editing rules (from the source project)

Keep data-composition-variables a 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.
