procedurally generated fish drawings

fishdraw

procedurally generated fish drawings. demo

• generates all sorts of weird fishes
• outputs polylines (supported format svg, json, csv, etc.)
• full procedural generation, single file no dependencies
• plotter-centric
• export drawing animation:

usage

basic

node fishdraw.js > output.svg

specify seed (from a string), speed of drawing and output format:

node fishdraw.js --seed "Biggus fishus" --format smil --speed 2 > output.svg

• the seed string is used as the name of the fish (printed in the drawing). If unspecified, a random pseudo-Latin name will be auto generated.
• the speed number is used to control the speed of drawing animation. Larger the number is, faster it draws. This option works only with format smil.
• format options: svg (regular svg), smil (animated svg), csv (each polyline on a comma-separated line) and json.

use as JS library:

const {fish,generate_params} = require('./fishdraw.js');
let polylines = fish(generate_params());
console.log(polylines);

fishdraw's Issues

How do users draw their favorite fish？

hi LingDong，

How can users draw their favorite fish, such as tuna, eel？

Maybe a custom JavaScript library can be used for drawing them, how to create and implement a custom JS library.

Thanks

Rendering of spots on the fish is very slow

Some fish are generated with tiny spots on them. When that happens rendering is slowed a lot.

Maybe a simpler method can be used for drawing them.

Is there any conceivable way to turn this into a screensaver?

I don't have the skill to do it myself, but there's something very restful about watching the drawings be completed, I feel it would be a good screensaver.
