(Original Image by Valerie Everett) It is sometime necessary to move an object in a physics simulation to a specific point. On the one hand, it can be difficult to analyse the exact force you have to apply; on the…
A cellular automata system is one of the best demonstrations of emergence. If you do not know what cellular automata (CA) is, then you should go download Conway’s Game of Life immediately: Conway’s Game of Life Essentially, CA is a…
(Photo by Darren Hester) Some algorithms take a long time to return their results. Whether it is because the algorithm has to operate on a huge data set, or because it has combinatorial complexity; every time you run it you…
Vector fields are used in certain AI and simulation techniques. The tool below allows you to paint a vector field. These files can be saved in XML format, that can easily be loaded into another application. Bookmark on Delicious Digg…
For many applications, detailed statistical models are overkill. Instead, we can get away with a rough description of the distribution – not in mathematical formula form, but just as a graph with a few sample points. For example, when trying…
