Differences Between 2D and 3D Simulations
The 2D simulation sub-league had its first release in early 1995 with version 0.1. It has been actively maintained since then with updates every few months. The ball and all players are represented as circles on the plane of the field. Their position is restricted to the two dimensions of the plane.
SimSpark, the platform on top of which the 3D simulation sub-league is built, was registered with SourceForge in 2004. The platform itself is now well established with ongoing development. The ball and all players are represented as articulated rigid bodies within a system that enforces the simulation of physical properties such as mass, inertia and friction.
As of 2010, a direct comparison of the gameplay of the 2D and 3D leagues shows a marked difference. 2D league teams are generally exhibiting advanced strategies and teamwork, whereas 3D teams appear to struggle with the basics of stability and ambulation. This is partly due to the difference in age of the two leagues, and partly to the difference in complexity involved in building agents for the two leagues. Replaying log files of finals over the recent years shows progress is being made by many teams.
In the 2D system, movement around the plane is achieved via commands from the agents such as move, dash, turn and kick. The 3D system has fewer command choices for agents to send, but the mechanics of motion about the field are much more involved as the positions of 22 hinges throughout the articulated body must be simultaneously controlled.

Famous quotes containing the words differences between and/or differences:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
