<h2>Example</h2>
<code>

var shape = new THREE.Shape();
shape.moveTo( 0,0 );
shape.lineTo( 0, width );
shape.lineTo( length, width );
shape.lineTo( length, 0 );
shape.lineTo( 0, 0 );
var extrudeSettings = {
steps: 2,
depth: 16,
bevelEnabled: true,
bevelThickness: 1,
bevelSize: 1,
bevelOffset: 0,
bevelSegments: 1
};
var geometry = new THREE.ExtrudeGeometry( shape, extrudeSettings );
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
var mesh = new THREE.Mesh( geometry, material ) ;
scene.add( mesh );
</code>
<h2>Constructor</h2>
<h3>[name]([param:Array shapes], [param:Object options])</h3>
<p>
shapes — Shape or an array of shapes. <br />
options — Object that can contain the following parameters.
<ul>
<li>curveSegments — int. Number of points on the curves. Default is 12.</li>
<li>steps — int. Number of points used for subdividing segments along the depth of the extruded spline. Default is 1.</li>
<li>depth — float. Depth to extrude the shape. Default is 100.</li>
<li>bevelEnabled — bool. Apply beveling to the shape. Default is true.</li>
<li>bevelThickness — float. How deep into the original shape the bevel goes. Default is 6.</li>
<li>bevelSize — float. Distance from the shape outline that the bevel extends. Default is bevelThickness - 2.</li>
<li>bevelOffset — float. Distance from the shape outline that the bevel starts. Default is 0.</li>
<li>bevelSegments — int. Number of bevel layers. Default is 3.</li>
<li>extrudePath — THREE.Curve. A 3D spline path along which the shape should be extruded.</li>
<li>UVGenerator — Object. object that provides UV generator functions</li>
</ul>
</p>
<p>
This object extrudes a 2D shape to a 3D geometry.
</p>
<p>
When creating a Mesh with this geometry, if you'd like to have a separate material used for its face
and its extruded sides, you can use an array of materials. The first material will be
applied to the face; the second material will be applied to the sides.
</p>
<h2>Properties</h2>
<p>See the base [page:Geometry] class for common properties.</p>
<h3>[property:Object parameters]</h3>
<p>
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
</p>
