# A Flower Made of Ink — `ink-flower@1.0.0`

A single indigo drop blooms into a detailed peony on cotton paper: petals unfurl, a calligraphic stem and veined leaves grow, and gold pollen rises.

One drop of indigo ink lands on warm cotton paper and blooms into a botanical peony. Forty-two overlapping petals open one by one, each with pooled pigment and fine veins; a calligraphic stem and two veined leaves grow downward; in the last seconds a few specks of gold pollen rise from the centre. It is a one-shot 12-second film that holds the finished flower. The film has no settings.

- Role: Shader film (three.js): Botanical ink wash, a finished 12-second portrait film with no settings.
- Implementation: three; entry `src/ink-flower.js`
- Files: https://aipixelwizard.com/registry/ink-flower/1.0.0/<path> (`LICENSE`, `asset.json`, `demo.js`, `index.html`, `src/ink-flower.js`)
- Manifest JSON: https://aipixelwizard.com/api/v1/visuals/ink-flower/versions/1.0.0
- Runnable demo: https://aipixelwizard.com/registry/ink-flower/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
- `createInkFlower() => { 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 12. 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: None: pigment on paper, with pooled darker edges and fine veins.
- Timing: A drop lands, the petals open one by one, the stem and leaves grow, and gold pollen rises in the last seconds.
- Works with: —
- Forty-two petals are timed individually, so the bloom never looks mechanical.
- The paper grain is fixed to the frame.
- Every pixel is a function of the time alone, so frames can be rendered in any order.

## Output and loop
- 1080×1350, 30 fps, 12 s, procedural
- Seamless loop: no — A one-shot film: it builds to a finished picture that holds to the last frame, so the end does not return to the start.
- 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

## Use it
New project: Create a WebGLRenderer on a canvas (no antialiasing), call createInkFlower() 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/ink-flower.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:
- Greeting video: the flower is complete by about 9 s, which leaves three seconds to hold with a message.
- Brand opener: a drop-to-bloom reveal that suits a logo landing on the empty paper.
- Calm background: hold the last frame as a still for a poster or a thumbnail.

## 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.
- The end does not return to the start, so repeating it is a hard cut.
