Detailed Description
A class that generates random terrains using Perlin noise functions.This class is responsible for generating the terrain in the world. It uses Perlin noise functions to create a somewhat realistic and smooth terrain. You do not need to understand how this code works in order to write a pathfinding AI.
This code is based on information on Perlin noise retrieved from www.siafoo.net/snippet/144 which was created by many authors. If you are interested in Perlin noise, consider looking into Ken Perlin's personal web page, which has all sorts of goodies.
