Automuse

Warning: This is very unfinished software, use at your own risk!

• Automatic UI generation
• Uses Parcel bundler with hot-reloading
• Save sketches and export renders from the UI

You can run Automuse with the --template flag to create your sketch based on a template (canvas, three, or random) or you can start from scratch.

npx automuse --template=random sketch.js

Every sketch has two exports, config and Sketch. Here's the random template for a simple example:

export const config = {
	width: 300,
	height: 300,
	seed: 'hello',
	frames: 1,
};

export class Sketch {
	constructor({ canvas }) {
		this.ctx = canvas.getContext('2d');
	}

	render({ width, height, random }) {
		const r = random() * 255,
			g = random() * 255,
			b = random() * 255;

		this.ctx.fillStyle = `rgba(${r}, ${g}, ${b}, 1.0)`;
		this.ctx.fillRect(0, 0, width, height);
	}
}

Running Automuse with this sketch will generate the following UI:

You can put whatever you like in the config object and Automuse will automatically generate a UI for it, so you can experiment interactively to find pleasing values. For example here's the three template:

Config

Some keys in the config object have special significance:

| Key | Description | Default | | ---- | ----------- | ------- | | width (required) | Width of the canvas | - | | height (required) | Height of the canvas | - | | frames | Number of frames to export | 300 | | fps | Frames per second when exporing | 30 | | exportWorkers | Number of Web Workers for exporting | 4 | | seed | Seed value for random function | "hello" |

The config object is provided to each sketch method as well as some extra values:

• frame: The frame number (starting at 0) since the sketch started.
• time: The time in seconds since the sketch started.
• random: A function you can call to get RNG values based on the configured seed.

Versions

At any time you can click the "Save" button to store a snapshot of the current config, a thumbnail, and the Git revision of your code.

The "View versions" screen shows all saved versions for the current sketch and allows you to view, load, and delete them. They are presented in a graph so it's super easy to keep track of your experimentation.

Exporting

Clicking on the "Export render" entry in the menu will allow you to choose between a few formats:

• PNG: If your sketch has multiple frames this will return a zip file of the frames named like 00000.png, 00001.png etc. (relies on the zip program being installed).
• GIF: Relies on ffmpeg being installed.
• MP4: Relies on ffmpeg being installed.

Similar projects

Automuse was mostly inspired by canvas-sketch and also bears many similarities to Processing / p5.js and the like.
