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

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 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 show you how to visualization the Lorenz Attractor in Processing.

Let's fly to new heights with a 3D terrain coding challenge! Using Perlin Noise and beginShape() + endShape() with triangle strips, I'll guide you through visualizing a 3D procedural terrain in Processing.

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

Solar System (3D)

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 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.
