War of the fireflies

lars — Mon, 21 Jan 2008 12:00:01 +0000

Derived from one of my older experiments: Three different populations of fireflies are fighting for their survival. If a firefly encounters an enemy fly, it tries to convert it to their tribe. The converted fly looses lifepoints and eventually dies during conversion. For the “collision logic”, I used a slightly modified version of Grant Skinners AS3 Proximitymanager. You can download the source and play around with it here (but don’t expect beautiful code ;)).

Box2D Physics Tests

Just a quick test with the AS3 port of the Box2D Physics Engine … it’s quite fun to play with, I could toss around boxes for hours ;)

Fluid Dynamics

After spending a lot time playing around with Plasma Pong I tried to do fluids by myself. I found a Fluid Solver and had just to convert it to C# and add a few Direct X effects. Download not yet available. Watch movie!

Conway’s Game of life

lars — Mon, 14 Aug 2006 15:37:18 +0000

My version of Conway’s game of life. The lifegame is a small cell-life simulation with these simple rules:

A cell with 0 or 1 neighbors dies, as if by loneliness.
A cell with 4 or more neighbors dies, as if by over-population.
Each cell with 2 or 3 neighbors survives.
An empty space with 3 neighbors becomes populated.

Yikes! How disgusting. mildew all over my site… Hope you can stop the spreading with your mouse: Launch!

Growing things

lars — Sat, 05 Feb 2005 09:30:28 +0000

The result of some random formulars:
x = Math.random() - Math.random(); y = Math.random() - Math.random();

lineTo(x, y);
Growing and dying forever… Launch!
