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.
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.
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.
