description: A wireframe portal bursts open, the title comes through, then its letters swap into a second phrase. HyperFrames block, 1920×1080, 8s, 9 variables.
---
# 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 [email protected] 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/[email protected]/dist/gsap.min.js`, `https://cdn.jsdelivr.net/npm/[email protected]/clipper.js`, `https://cdn.jsdelivr.net/npm/[email protected]/build/three.module.js`, `https://cdn.jsdelivr.net/npm/[email protected]/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.
