In this two part challenge, I cover beginShape(), endShape(), and texture(), TRIANGLE_STRIP, QUAD_STRIP, and more. I combine these geometry functions with the Toxiclibs physics library to simulate a waving flag (with a unikitty image texture!)

I love all things random and chance so why not make a Plink simulation with the matter.js physics engine and p5.js!

In this coding challenge, I attempt to create a "Fractal Spirograph" with Processing (Java). The visuals are inspired by images and explanation on C. J. Chen’s blog.

Inspired by Everest Pipkin’s Moth Generator, I use trigonometry and perlin noise to procedurally generate butterfly wing designs with p5.js.

In this coding challenge, I look at extracting font path points from text in p5.js with p5.Font.textToPoints(). I render the text as particles with steering behaviors that react to the mouse.

In this coding challenge, I follow up on the Earthquake Data Visualization challenge and create a 3D version in Processing(Java) using spherical coordinates. I also discuss some 3D vector math including the cross product.

In this coding challenge, I visualize earthquake data from the USGS by mapping the latitude, longitude and the magnitude of earthquakes with p5.js. The map imagery is pulled from mapbox and the math demonstrated converts latitude, longitude to x,y via Web Mercator.
