Challenges

Building off of the previous coding challenge (2D Ray Casting) I attempt to make my own version the original Wolfenstein 3D Raycasting engine and visualize the "field of view" of the moving particle.

In this coding challenge, I visualize a 4D Hypercube (aka "Tesseract") in Processing (Java).

Can I draw and rotate a 3D cube using Processing's 2D renderer with just some math?!?! Yes! Watch to learn more about rotation and projection matrices along with perspective and orthographic projection!

The artist BeesandBombs makes amazing algorithmic looping GIFs! Here's my attempt to recreate one of my favorite GIFs in JavaScript with p5.js and the WEBGL renderer.

Getting tied up in 3D Knots in Processing is loads of fun! Thank you to Paul Bourke for the helpful reference and formulae!

In this 4th of July themed coding challenge, I build an HTML5 canvas fireworks simulation from scratch using the p5.js JavaScript library. I also show how to use Processing to create 3D Fireworks.

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.

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