Chalks

A thin, independent library on top of p5js containing methods to manipulate points and draw figures.
Chalks is fully compatible with p5js and just provides some handy tools to simplify the creation process by accessing the p5js canvas2d object.

Some of the components:

• Simplified path object to define styles and curves in a functional, declarative way.
• Generative:
  • Butterfly curve
  • Hypocycloid
  • Rose
  • Rossler
  • Lorentz
  • Dejon
  • Voronoi points (thanks to voronoi)
• Points manipulation (subdivide, subchunks)
• Layout functions: column, rows, masonry
• Grammars
• Color handling using Chromajs

Installation

npm i chalks

Keep in mind that chalks requires p5js to be present.
You can reference the chalks.min.js library contained in the node_modules folder in your index.html:

<script language="javascript" type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.7.1/p5.js"></script>
<script language="javascript" src="./node_modules/chalks/dist/chalks.min.js" type="text/javascript"></script>
<script language="javascript" src="_your_sketch_.js" type="text/javascript"></script>

Alternatively you can simply clone this repo and add chalks.min.js, e.g.
Copy the file chalks.min.js from /lib and add it to your index.html after your p5js import.

Example:

<script language="javascript" type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.7.1/p5.js"></script>
<script language="javascript" src="./chalks/dist/chalks.min.js" type="text/javascript"></script>
<script language="javascript" src="_your_sketch_.js" type="text/javascript"></script>

Example

function setup() {
    ch = new Chalks({width: 1000, height: 1000, seed:4}, {fill:"c8c8c8"})
    points = ch.Parametrics.dejon({x:500, y:900}, -2.24, 0.43, -3.266, -8.23, 250, 6200)
    console.log(points)
}

function draw() {
    points.forEach(p => ch.path({fill:"red", alpha:random(), stroke:"black", strokeWidth:12}, 10).m(p).l(p, p.cadd(150, 50)).draw())
    noLoop()
}
