# The Silver Swan — `chrome-swan@1.0.0`

A heavy silver droplet draws itself into a long-necked swan above a black mirror, then pulls back into a drop. Liquid chrome with real reflections. Loops.

A single heavy droplet of liquid silver hangs above a rippling black mirror. It stretches and folds into a long-necked swan with folded wings, tooled feathers and one tiny ruby eye, with white architectural reflections running down its neck and a mirrored twin in the black water below. The swan holds, then pulls back into the droplet, so the film ends where it began and loops. The film has no settings.

- Role: Shader film (three.js): Liquid chrome luxury surrealism, a finished 8-second portrait film with no settings.
- Implementation: three; entry `src/chrome-swan.js`
- Files: https://aipixelwizard.com/registry/chrome-swan/1.0.0/<path> (`LICENSE`, `asset.json`, `demo.js`, `index.html`, `src/chrome-swan.js`)
- Manifest JSON: https://aipixelwizard.com/api/v1/visuals/chrome-swan/versions/1.0.0
- Runnable demo: https://aipixelwizard.com/registry/chrome-swan/1.0.0/index.html (open over http; it imports sibling packages by relative path)
- Dependencies (exact): `three@0.185.1` (source) — Renderer and a full-screen shader material.; `apw-runtime@1.0.0` (demo) — Demo harness.

## Exports
- `createChromeSwan() => { scene, camera, setSize(width, height), update(time), dispose() }` — The film as one full-screen shader; render its scene with its camera straight to the canvas.

## Composition
- Inputs: The time in seconds, 0 to 8. The film has no other settings.
- Outputs: An opaque full-frame picture, already in display colours: render it straight to the canvas.
- Coordinates: Composed for a 4:5 portrait frame and measured by the frame height: in a wider frame the picture stays centred at full height and its background fills the sides; in a narrower one, such as 9:16, the sides are cropped.
- Lighting: A dark studio: soft white strip reflections on the chrome and a black mirror floor that reflects the swan.
- Timing: A droplet draws itself into a swan, the swan holds and the wings fold, then it pulls back into the droplet.
- Works with: —
- The reflection in the black water is drawn from the same geometry, so it moves with the swan.
- The metal is one continuous, smoothly blended surface, not separate parts.
- Every pixel is a function of the time alone, so frames can be rendered in any order.

## Output and loop
- 1080×1350, 30 fps, 8 s, procedural
- Seamless loop: yes — Every part of the film is a function of the time modulo its length, and every motion completes whole cycles, so the last frame meets the first.
- Verified 2026-10-10 in Chrome 154.0.8037.97 headless on Linux 7.0.0-38-generic (x64), Node 22.14.0 (WebGL 2 via SwiftShader (software)); deterministic: yes; loop check: Frame 0 vs end state (progress 1): mean |Δ| 0.0000, max |Δ| 0 of 255.

## Use it
New project: Create a WebGLRenderer on a canvas (no antialiasing), call createChromeSwan() once and film.setSize(width, height); then for each frame call film.update(timeInSeconds) and renderer.render(film.scene, film.camera).

Existing project: Copy src/chrome-swan.js, which needs only three. Render film.scene with film.camera into your own canvas or render target; the output is opaque and already in display colours, so use no tone mapping or colour conversion.

Reuse ideas:
- Luxury teaser: loop it behind a logo; the swan stands fully formed through the middle of the film.
- Seamless loop: it ends on the droplet it started from, so it can repeat for any length.
- Beauty and fashion reels: the dark frame leaves room for a title above the swan.

## Limitations
- The film is finished: it has no settings. To change colours or timing, edit the shader.
- It is composed for a 4:5 portrait frame.
- Its length is fixed at 8 seconds; repeat the loop to fill a longer clip.
