		<p class="desc">
			A loader for Rhinoceros 3d files and objects. <br /><br />
			Rhinoceros is a 3D modeler used to create, edit, analyze, document, render, animate, and translate NURBS curves, surfaces, solids, point clouds, as well as polygon meshes and SubD objects.
			[link:https://github.com/mcneel/rhino3dm rhino3dm.js] is compiled to WebAssembly from the open source geometry library [link:https://github.com/mcneel/opennurbs openNURBS].

		<h2>Code Example</h2>

		<code>
		// Instantiate a loader
		var loader = new Rhino3dmLoader();

		// Specify path to a folder containing WASM/JS libraries.
		loader.setLibraryPath( '/examples/jsm/libs/rhino3dm/' );

		// Load a 3DM file
		loader.load(
			// resource URL
			'model.3dm',
			// called when the resource is loaded
			function ( object ) {

				scene.add( object );

			},
			// called as loading progresses
			function ( xhr ) {

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

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

				console.log( 'An error happened' );

			}

		<h2>Constructor</h2>

		<h3>Rhino3dmLoader( [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 Rhino3dmLoader.
		</p>

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

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

		<h3>[method:null 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 <em>.3dm</em> file.<br />
		[page:Function onLoad] — A function to be called after the loading is successfully completed.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, that contains .[page:Integer total] and .[page:Integer loaded] bytes.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives error as an argument.<br />
		</p>
		<p>
		Begin loading from url and call the <em>onLoad</em> function with the geometry.
		</p>

		<h3>[method:this setLibraryPath]( [param:String value] )</h3>
		<p>
		[page:String value] — Path to folder containing the JS and WASM libraries.
		</p>

		<h3>[method:this setWorkerLimit]( [param:Number workerLimit] )</h3>
		<p>
			[page:Number workerLimit] - Maximum number of workers to be allocated. Default is 4.<br />
		</p>
		<p>
		Sets the maximum number of [link:https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers Web Workers]
		to be used during decoding. A lower limit may be preferable if workers are also for other tasks
		in the application.
		</p>

		<h3>[method:this dispose]()</h3>
		<p>
		Disposes of the loader resources and deallocates memory.
