		</p>

		<h2>代码示例</h2>

		<code>

		// instantiate a loader
		var loader = new PCDLoader();

		// load a resource
		loader.load(
			// resource URL
			'pointcloud.pcd',
			// called when the resource is loaded
			function ( mesh ) {

				scene.add( mesh );

			},
			// called when loading is in progresses
			function ( xhr ) {

				console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

			},
			// called when loading has errors
			function ( error ) {

				console.log( 'An error happened' );

		<p>
		[page:String url] — A string containing the path/URL of the <em>.pcd</em> file.<br />
		[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives loaded [page:Object3D] as an argument.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.<br />
