fractal terrain generator
online demo: http://qiao.github.com/fractal-terrain-generator/demo/
This program is based on the Diamond-Square algorithm. Check out http://gameprogrammer.com/fractal.html for a detailed description.
var terrain = generateTerrain32 32 1.0;
generateTerrain receives three parameters:
width: Segments of the width of the terrain.
height: Segments of the height of the terrain.
smoothness: Smoothness of the terrain. Higher this value, smoother the terrain will be. Recommended value is 1.
terrain will be a (width + 1) x (height + 1) 2-dimensional array containing the elevations of each vertex. And each elevation will be between -1 and 1.
