		<h1>[name]</h1>

		<p class="desc">
			A loader for the PCD (Point Cloud Data) file format. [name] supports ASCII and (compressed) binary files as well as the following PCD fields:
			<ul>
				<li>x y z</li>
				<li>rgb</li>
				<li>normal_x normal_y normal_z</li>
				<li>intensity</li>
				<li>label</li>
			</ul>
		</p>

		<h2>Code Example</h2>

		<code>

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

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

				scene.add( points );

			},
			// 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' );

			}
		);
		</code>

		<h2>Constructor</h2>

		<h3>[name]( [param:LoadingManager manager] )</h3>
		<p>
		[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
		</p>
		<p>
		Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Loader] class for common properties.</p>

		<h3>[page:Boolean littleEndian]</h3>
		<p>
		Default value is true.
		</p>

		<h2>Methods</h2>
		<p>See the base [page:Loader] class for common methods.</p>

		<h3>[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
		<p>
		[page:String url] — A string containing the path/URL of the `.pcd` 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. If the server does not set the Content-Length header; .[page:Integer total] will be 0.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
		</p>
		<p>
		Begin loading from url and call onLoad with the parsed response content.
		</p>

		<h3>[method:Object3D parse]( [param:Arraybuffer data],[param:String url] )</h3>
		<p>
		[page:Arraybuffer data] — The binary structure to parse.
		</p>
		<p>
		[page:String url] — The file name or file url.
		</p>
		<p>
		Parse an `pcd` binary structure and return an [page:Object3D].<br />
		The object is converted to [page:Points] with a [page:BufferGeometry] and a [page:PointsMaterial].
