Help explaining me some code
Dec 15th, 2008, 2:13am  
Hello everyone!
I would really apreciate if someone could help me understand how this was made: http://www.openprocessing.org/visuals/applets/visual4ef45330aeaf226e23ee10881076b58c/

There are links there to the code, but i dont really understand it. I see there are various files that are created classes in them but i need a little help to understanding what exactly are they doing because i'm am a very beginner user.

Can somebody please help.

Vector3D is a generic class, a vector in space, with a number of properties (mostly coordinates, and derived properties like length) and methods (in general, maths with other vectors or get properties).
Note that recent versions of Processing introduced PVector which is basically the same thing (with documentation!).

From a quick look, it appears that this sketch uses it only as a Vector2D, ie. on a plane, and apparently only to hold a pair of values (x, y). Somehow, attractor could have been an extension of Vector3D.
