**dat.gui** is a lightweight controller library for JavaScript. It allows you to easily manipulate variables and fire functions on the fly.
Check the [index page](http://dataarts.github.com/dat.gui/) for usage.
Initiated by [George Michael Brower](http://georgemichaelbrower.com/) and [Jono Brandel](http://jonobr1.com/) of the Data Arts Team, Google Creative Lab.

<p><strong>dat.gui</strong> is a lightweight controller library for JavaScript.
It allows you to easily manipulate variables and fire functions on the fly.

&lt;script type='text/javascript'&gt;
window.onload = function() {

};
&lt;/script&gt;
</pre>
<ul id='desc'>
<li><code>DAT.GUI</code> will infer the type of the property you're trying
to add<br/>
(based on its initial value) and create the corresponding control.
</li>
<li>The properties must be public, i.e. defined by <code><strong>this</strong>.prop
= value</code>.
</li>
</ul>
<!--
<h2 class='collapsed'>Fire a function when someone uses a control</h2>

<!--<h2 class='section'>Saving your parameters</h2>-->
<!--<div class='collapsable'>-->
<!--<div>-->
<!--<p>The simplest way to save your parameters is via-->
<!--<code>DAT.GUI.saveURL()</code>. This method directs your browser to a-->
<!--URL containing the current GUI settings.</p>-->
<!--<pre class='prettyprint last'>-->
<!--// Make a button for the url function-->
<!--gui.add(DAT.GUI, 'saveURL');</pre>-->
<!--</div>-->

<!--<div class='collapsed'>-->
<!--<h2 class='section'>Advanced saving</h2>-->
<!--<div class='collapsable'>-->
<!--<div>-->
<!--<p>Let's say you'd like to share your settings with someone. Instead of-->
<!--sending a long link with lots of parameters stored in it, you can make-->
<!--your saved settings the defaults.</p>-->
<!--<p>First, add the method <code>DAT.GUI.showSaveString()</code> to a gui-->
<!--object:</p>-->
<!--<pre class='prettyprint'>var gui = new DAT.GUI();-->
<!--// Add some stuff (and pretend I change their values);-->
<!--gui.add(someObject, 'someProperty');-->
<!--gui.add(someObject, 'someOtherProperty');-->
<!--// Make a save button.-->
<!--gui.add(DAT.GUI, 'showSaveString');</pre>-->
<!--<p>Clicking the 'showSaveString' button bring up an alert with a string.-->
<!--Copy and paste that string into the method <code>DAT.GUI.load()</code>-->
<!--before you instantiate any gui objects.</p>-->
<!--<pre class='prettyprint'>-->
<!--// Replace COPIED STRING with the value you got from showSaveString()-->
<!--DAT.GUI.load('COPIED STRING');-->
<!--var gui = new DAT.GUI();-->
<!--// Now these properties will be set to the values you just saved.-->
<!--gui.add(someObject, 'someProperty');-->
<!--gui.add(someObject, 'someOtherProperty');</pre>-->
<!--<p class='last'><strong>Save strings won't work if you change the order in-->
<!--which you've added properties to your gui objects, or the order of the-->
<!--gui objects themselves.</strong>. If you want to add more parameters to-->
<!--your gui and use an old save string, make sure they're added after the-->
<!--properties whose values you've saved.</p>-->
<!--</div>-->
<!--</div>-->

<div class='collapsed'>
<h2 class='section'>Choosing from a list of values</h2>
<div class='collapsable'>
<div>
<pre class='prettyprint first last'>gui.add(obj, 'propertyName').options(1, 2, 3, 5, 8);
// Alternatively, you can specify custom labels using object syntax
gui.add(obj, 'propertyName').options({'Small': 1, 'Medium': 2, 'Large': 3});
</pre>
</div>
</div>
</div>
<div class='collapsed'>
<h2 class='section'>Listen for variable changes inside the GUI</h2>
<div class='collapsable'>
<div>
<p>To fire a function whenever a user changes a variable via the GUI, use
the following syntax:</p>
<pre class='prettyprint'>gui.add(obj, 'propertyName').onChange(function(newValue) {
alert('You changed me to ' + newValue);
});</pre>
<p>This can be slightly annoying for types like number or string. You may
not want to fire a function while the user is sliding, or while they're
typing. To fire a function when the user has <em>finished</em> making
changes, use the following:</p>
<pre class='prettyprint'>gui.add(obj, 'propertyName').onFinishChange(function(newValue) {
alert('You just finished changing me to ' + newValue);
});</pre>
<p>Finally, if you'd like to do a little something extra when a function
is called, use the following:</p>
<pre class='prettyprint last'>gui.add(obj, 'functionName').onFire(function() {
alert('You called a function with dat.gui');
});</pre>
</div>
</div>
</div>
<div class='collapsed'>
<h2 class='section'>Listen for variable changes outside of the GUI</h2>
<div class='collapsable'>
<div>
<p>Let's say you have a variable that changes by itself from time to time.
If you'd like the GUI to reflect those changes, use the <code>listen()</code>
method.</p>
<pre
class='prettyprint last'>gui.add(obj, 'changingProperty').listen();</pre>
</div>
</div>
</div>
<div class='collapsed'>
<h2 class='section'>Advanced listening</h2>
<div class='collapsable'>
<div>
<p>By default, <code>DAT.GUI</code> will create an internal interval
that checks for changes in the values you've marked with
<code>listen()</code>. If you'd like to check for these changes in an
interval of your own definition, use the following:</p>
<pre class='prettyprint'>
gui.autoListen = false; // disables internal interval
gui.add(obj, 'changingProperty').listen();
// Make your own loop
setInterval(function() {
gui.listen(); // updates values you've marked with listen()
}, 1000 / 60);</pre>
<p>Alternatively, you can forego calling <code>listen()</code> on
individual controllers, and instead choose to monitor changes in
<em>all</em> values controlled by your gui.</p>
<pre class='prettyprint last'>
gui.autoListen = false; // disables internal interval
gui.add(obj, 'add');
gui.add(obj, 'lotsa');
gui.add(obj, 'properties');
// Make your own loop
setInterval(function() {
gui.listenAll(); // updates ALL values managed by this gui
}, 1000 / 60);</pre>
</div>
</div>
</div>
<div class='collapsed'>
<h2 class='section'>Multiple panels and custom placement</h2>
<div class='collapsable'>
<div>
<p>You can instantiate multiple <code>DAT.GUI</code> objects and name them
however you'd like.</p>
<pre class='prettyprint'>var gui1 = new DAT.GUI();
var gui2 = new DAT.GUI();
// The name function overwrites the 'Show Controls' text.
gui1.name('Utilities');
gui2.name('Camera Placement');</pre>
<p>By default, <code>DAT.GUI</code> panels will be automatically added
to the HTML document and fixed to the top of the screen from right to
left. You can disable this behavior and append the gui DOM element to
a container of your choosing.</p>
<pre class='prettyprint last'>
// Notice this belongs to the DAT.GUI class (uppercase)
// and not an instance thereof.
DAT.GUI.autoPlace = false;
var gui = new DAT.GUI();
// Do some custom styles ...
gui.domElement.style.position = 'absolute';
gui.domElement.style.top = '20px';
gui.domElement.style.left = '20px';
document.getElementById('my-gui-container').appendChild( gui.domElement );</pre>
