Contention

Contention

processing java application, april 2009

The premise is simple. I wanted to trace particles as they race towards another particle with the intention of destroying them. Got the idea from the opening scene of Lord of the Rings:The Fellowship of the Ring.

I read somewhere that Steve Jackson had computer programmers create an algorithm to simulate the opening war scene of the movie. Instead of rendering each soldier by hand, he had the effects team create elves that would react when the orcs approach them. This saved time on rendering but it probably ate up CPU.

The concept for Contention is similar. Two teams of particles race towards another particle of the opposing team. Each particle is strengthened by their teammates around them. The more teammates around them, the stronger they are. Once they reach the opposing target, they "roll dice" to see who wins based on their strengths. If the particle wins, they choose another target. If they lose, they start over.

Some basic behaviors were programmed to each particle. Each particle draws a line to any other particle near it. The color of the line is the average of both or all particles around it. Lines are also drawn between the particle and its target particle.

The algorithm was quite simple and this only really took about a couple of hours to draw up. I had some old class files that I reused for this so this was pretty quick and gratifying.

Below are other images created by the algorithm. The original size of each creation is 4800x3600.
