This is a command line tool to generate and render chaotic attractors with JavaScript.
Clone this repository and then run
npm i
npm i -g
The CLI will be available as infinite-chaos, see usage.
This project depends on node-canvas library which itself relies on operating system (OS) dependent libraries, therefore depending on OS and computer hardware, some external libraries may need to be installed.
Install Cairo using brew:
brew install pkg-config cairo pango
Usage: infinite-chaos [options]
Command line tool to generate and render chaotic attractors
Options:
-V, --version output the version number
-s, --seed [seed] Seed for the attractor parameters. Also support inclusion of modifiers in
seed_fn_fn format (i.e. abcdef_sin_cos).
-m, --mine Mine attractor parameters by automatically generating parameters.
-n, --pointCount [count] Number of points to generate the attractor.
-d, --mods [mods] Modifier functions for the x and y coordinates in fn/fn format (i.e. sin/cos).
-c, --color [color] Rendering color.
-b, --background [background] Rendering background color.
-w, --width [width] Rendering width.
-h, --height [height] Rendering height.
-r, --marginRatio [ratio] Rendering margin ratio.
-a, --opacity [opacity] Rendering opacity.
-o, --output [path] Rendering output directory.
-q, --quality [quality] Rendering output quality from 0 to 100 (default: 90).
-f, --filter [filter] Spread filtering level to skip the rendering of clustered outputs from 0 to 1
(default: 0.2).
-C, --cpus [cpus] Number of CPU cores to use for mining.
