David Hagar's Projects

apollonian-circles

Draws a set of tangential circles similar to a Smith Chart (just because it looks cool) . More info at http://en.wikipedia.org/wiki/Smith_chart and http://en.wikipedia.org/wiki/Apollonian_circles

cracks

Java code that simulates the cracks that form when mud dries or paint cracks.

cubedots

Java code that renders alignment patterns in a 3D grid of dots

Disk Life does a 2-d pool table like simulation on "Disk Creatures". Most of the time in this program went into the physics simulation and not the creatures. The physics engine does a time accurate collision model ( event model with time of collision calculated ). The collision detection algorithm is a "sift and prune" O(N) algorithm whereas brute force pairwise algorithms are O(N^2). The creatures react simply by getting damaged from a collision and create a spring connecting any two colliding disks that can break if stretched too far. When a creature dies an energy disk is created in its place.

evolutionweasel

A hacky implementation of Dawkin's "Me thinks it looks like a weasel" program

evolving-text

Evolves a random string into a goal string. Its based on the "weasel program" written about by Richard Dawkins.

$fractal-feedback icon$ fractal-feedback

Uses Three.js/WebGL to recursively grab the screen and render it back slightly transformed. This is similar to video feedback techniques for creating fractals.
