You may check out http://gameprogrammer.com/fractal.html for a detailed description.

## Usage ##

### Browser ###

download http://qiao.github.com/fractal-terrain-generator/lib/terrain.js and include it in your html.

### Node.js ###

    npm install 

```javascript
var terrain = generateTerrain(32, 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.

The result `terrain` will be a (width + 1) x (height + 1) 2-dimensional array containing the elevation of each vertex.
