Procedural Art

Procedural Space Invaders

Procedural Space Invaders

These simple procedurally-generated Space Invaders-style sprites were directly inspired by Jared Tarbell’s classic Invader Fractal. The concept is straightforward: start with a grid of a set width and height (3×5 works well), and mirror on the x all tiles except for the center one. You can see it in action here and grab the source code from GitHub.

Procedural Radial Flowers

Procedural Radial Flowers

At my wife’s request I bring you a direct spin off of the Procedural Space Invaders, only this time rotated along a center axis to create procedural radial spirals, or “flowers”. You can see it in action here and grab the source code from GitHub.

Experimenting with Bézier Curves

Experimenting with Bézier Curves

A few days ago, I stumbled upon the Wikipedia Article on Bézier Curves. As a fan of procedurally generated art, when I saw the fifth-order Bézier curve animation within that article, I was inspired to attempt my own Bézier curve drawing algorithm. This is what happened. In this article, on ANidea, I break down a basic Bézier curve algorithm and show how it can be generalized to create Nth order Bézier curves.
