# Wireframe Portal Title

Extruded wireframe letterforms are built from the bundled Geist face with a TTF loader and polygon offsetting, then revealed through a portal burst whose chaos is a variable. A second beat swaps the letters into a replacement phrase with whole-word wrapping and auto type size, staggered with a tunable easing curve and settle glitch, with optional depth fog.

Composition id: `wireframe-portal-title`. Duration 8 s at 30 fps, 1920×1080.

## Files

- `wireframe-portal-title.html` (63 KB)
- `assets/fonts/Geist-Bold.ttf` (65 KB)
- `assets/fonts/Geist-Regular.ttf` (65 KB)
- `assets/fonts/Geist-SemiBold.ttf` (65 KB)
- `assets/fonts/Geist-OFL.txt` (4 KB)

## Install

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

```html
<div
  data-composition-id="wireframe-portal-title"
  data-composition-src="compositions/wireframe-portal-title/wireframe-portal-title.html"
  data-start="0"
  data-duration="8"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>
```

Render with custom values by targeting the composition file directly:

```sh
npx --yes hyperframes@0.8.12 render 'compositions/wireframe-portal-title/wireframe-portal-title.html' --variables '{"title":"BREAKTHROUGH","replacementPhrase":"Lets do this sir!"}'
```

## 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                                       |
| ------------------- | ------- | ---------------------------- | --------------------------------------------------- |
| `title`             | string  | `"BREAKTHROUGH"`             | Title max 18 chars                                  |
| `replacementPhrase` | string  | `"Lets do this sir!"`        | 3D replacement phrase (auto layout)                 |
| `phraseDuration`    | number  | `1.85`                       | Phrase transition duration (s) 0.65–2.9 step 0.05   |
| `phraseEasing`      | number  | `8`                          | Transition easing (1 gentle – 8 snap) 1–8 step 0.25 |
| `settleGlitch`      | number  | `0.2`                        | Letter settle glitch strength 0–4 step 0.05         |
| `depthFog`          | boolean | `true`                       | Depth fog (early fade always on)                    |
| `subtitle`          | string  | `"HYPERFRAMES PORTAL TITLE"` | Subtitle max 48 chars                               |
| `accent`            | color   | `"#F5C518"`                  | Accent                                              |
| `burstChaos`        | number  | `1`                          | Burst chaos (0-2) 0–2 step 0.01                     |

## Runtime contract

- One paused GSAP timeline registered as `window.__timelines["wireframe-portal-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, GSAP 3.14.2, Canvas 2D, GLSL shaders, Post-processing, Seeded PRNG, Clipper. 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/clipper-lib@6.4.2/clipper.js`, `https://cdn.jsdelivr.net/npm/three@0.181.2/build/three.module.js`, `https://cdn.jsdelivr.net/npm/three@0.181.2/examples/jsm/`.
- Local fonts: assets/fonts/Geist-Regular.ttf, assets/fonts/Geist-SemiBold.ttf, assets/fonts/Geist-Bold.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.

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,

however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
