Perlin noise

In this multi-part coding challenge I show how to use a noise field and polar coordinates to create a perfect GIF loop.

Polar Noise Loops

In this coding challenge, I implement a pixel-based β€œfire” algorithm using Processing (Java).

Let's attempt to create a snowfall simulation using p5.js, sprite sheets and Perlin noise wind!


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 simulate a blob-like shape with wobbly edges using beginShape(), endShape(), polar coordinates, and perlin noise.


In this coding challenge, I use Perlin noise to create a two-dimensional flow field with the p5.js library.
