<h2>Maze generators</h2>

<p>This family of algorithms uses the following callback values:</p>
<ul>
	<li><code>0</code>: empty space</li>
	<li><code>1</code>: wall</li>
</ul>

<h3>DividedMaze</h3>

<p>Based on a <a href="http://en.wikipedia.org/wiki/Maze_generation_algorithm#Recursive_division_method">Recursive division method</a>.</p>

<div class="example">
var w = 39, h = 25;
var dm = new ROT.Map.DividedMaze(w, h);

for (var i=0; i&lt;4; i++) {
	var display = new ROT.Display({width:w, height:h, fontSize:6});
	SHOW(display.getContainer());

	dm.create(display.DEBUG);
}
</div>

<h3>Icey's Maze</h3>

<p>Cool mazes with a configurable regularity can be created using this <a href="http://www.roguebasin.roguelikedevelopment.org/index.php?title=Simple_maze#Maze_Generator_in_Visual_Basic_6">algorithm</a>, 
taken from a Rogue Basin wiki. Regularity is an integer value, specified as a third argument; 0 = most random.</p>

<div class="example">
var w = 39, h = 25;

for (var i=0; i&lt;4; i++) {
	var display = new ROT.Display({width:w, height:h, fontSize:6});
	SHOW(display.getContainer());

	var maze = new ROT.Map.IceyMaze(w, h, 4*i);
	maze.create(display.DEBUG);
}
</div>

<h3>Eller's Perfect Maze</h3>

<p>For a full explanation of this wonderful Eller's algorithm, please see 
<a href="http://homepages.cwi.nl/~tromp/maze.html">http://homepages.cwi.nl/~tromp/maze.html</a>. 
Not only it generates a <em>Perfect maze</em> (every two cells are connected by exactly one path), 
but it only requires 2*N memory to generate a maze of N*N size!</p>

<div class="example">
var w = 39, h = 25;
var em = new ROT.Map.EllerMaze(w, h);

for (var i=0; i&lt;4; i++) {
	var display = new ROT.Display({width:w, height:h, fontSize:6});
	SHOW(display.getContainer());

	em.create(display.DEBUG);
}
</div>
