In this coding challenge, I use the "superformula" to make a 3D "supershape" in Processing. This is part 4 of a multi-part series on superformulas, superellipses and supershapes

3D Supershapes

In this coding challenge, I create a sphere in Processing using spherical coordinates and triangle strips. This is the 3rd part of a multi-part series on superformulas, superellipses and supershapes.

Spherical Geometry

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

In this coding challenge, I show you how to make 2D supershapes in p5.js.

Boing! Using some particles and some springs with the Toxiclibs physics library, I create a 3D cloth simulation in Processing. Toxiclibs can now be downloaded from Processing's library manager.

In this coding challenge, I’m going to use superformulas to create a superellipse in p5.js. This is part 1 of a multi-part series on superformulas, superellipses and supershapes.

More algorithmic botany! Another way to generate a fractal tree is to consider every part of the tree an object, so that we can apply forces and attributes to all the branches and leaves and more!

Object-Oriented Fractal Trees

In this coding challenge, I'm building on top of the Space Colonization video and creating a 3D Fractal Tree, using the same algorithm, in Processing.

3D Fractal Trees

In this third installment of my series on algorithmic botany, I discuss L-systems and how they can be used to generate trees and other fractal patterns in p5.js.

Fractal Trees - L-System

In this coding challenge, I'm using the space colonization algorithm to make a tree generator. This is the 4th part of my algorithmic botany series.

Space Colonization

In this coding challenge, I'm implement fractal trees with recursion in p5.js. This is the first part of a series on algorithmic botany.

Recursive Fractal Trees

In this coding challenge, I visualize a Reaction Diffusion simulation using the Gray Scott model in JavaScript (with the p5.js library).

In this coding challenge, I show you how to visualization the Lorenz Attractor in Processing.

Choo choo! In this multi-part coding challenge, I create a maze generator using a depth-first search algorithm with recursive backtracking. The idea is to walk through a grid of cells, removing walls as we go to build a maze.

In the second part of this coding challenge, using Processing, I take the code from the 2D Solar System and turn it three-dimensional.

In part 3 of this coding challenge, using Processing, I add textures to the 3D objects created in part 2. The PShape class and createShape() functions are covered.

In this viewer submitted coding challenge, I make a 2D Solar System Generator in Processing.

In this viewer submitted coding challenge, I program a cellular mitosis simulation in p5.js.

This is my attempt to make a Space Invaders type game in the browser with JavaScript and the p5.js library

In this viewer submitted coding challenge, I attempt to code a Purple Rain Simulator in Processing.

In this coding challenge, I code a p5.js version of the Snake Game.

In this coding challenge, I attempt to code the Menger Sponge (fractals) using Processing.

This is the first in a new series of videos. In this video I attempt to program a "star field" or "warp speed" visualization in Processing.
