Let’s draw some squares!
Last week I introduced Clojure as a possible replacement for Javascript for my generative art pursuits. Clojure has the Quil library that provides many of the same capabilities that p5.js provides to Javascript. Let’s look at a simple example. This Javascript/p5.js program generates an image like the one at the top of this post.
function setup() { createCanvas(800, 800); background(240); stroke(0); let size = 500; let offset = 50; let centerX = width/2; let centerY = height/2; let topLeftX = centerX - size/2; let topLeftY = centerY - size/2; fill(200, 150, 250, 150); rect(topLeftX, topLeftY, size, size); rect(topLeftX-offset, topLeftY-offset, size, size); rect(topLeftX+offset, topLeftY+offset, size, size); } The program is fairly simple: create the canvas, fill in the background with grey, set the stroke (line) color to black, set the fill color, and draw three rectangles slightly offset from each other.
