[name]

A loader for loading a [page:Scene] from a JSON resource.

Constructor

[name]( [page:LoadingManager manager] )

[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].

Creates a new [name].

Properties

Methods

[method:null load]( [page:String url], [page:Function onLoad], [page:Function onProgress], [page:Function onError] )

[page:String url] — required
[page:Function onLoad] — Will be called when load completes. The argument will be an [page:Object] containing the loaded components.
[page:Function onProgress] — Will be called while load progresses. The argument will be the XmlHttpRequest instance, that contain .[page:Integer total] and .[page:Integer loaded] bytes.
[page:Function onError] — Will be called when load errors.

Begin loading from url and call onLoad with the parsed scene.

[method:Object parse]( [page:Object json], [page:Function callbackFinished], [page:String url] )

[page:Object json] — The JSON structure to parse.
[page:Function callbackFinished] — Will be called when parse completes.
[page:String url] — Will be used as base for assets' relative URLs.

Parse a JSON scene description and return a new [page:Object] with fully instantiated Three.js objects.

[method:null setCrossOrigin]( [page:String value] )

[page:String value] — The crossOrigin string to implement CORS for loading the url from a different domain that allows CORS.

[method:null addGeometryHandler]( [page:String typeID], [page:Function loaderClass] )

[page:String typeID] — The type to handle.
[page:Function loaderClass] — The handler class.

Add an handler for a specific geometry type.

[method:null addHierarchyHandler]( [page:String typeID], [page:Function loaderClass] )

[page:String typeID] — The type to handle.
[page:Function loaderClass] — The handler class.

Add an handler for a specific object type.

Example


		// instantiate a loader
		var loader = new THREE.SceneLoader();

		// Handle STL geometries
		loader.addGeometryHandler( "stl", THREE.STLLoader );

		// Handle OBJ objects
		loader.addHierarchyHandler( "obj", THREE.OBJLoader );

		// load a JSON resource
		loader.load(
			// resource URL
			'scenes/test_scene.js',
			// Function when resource is loaded
			function ( result ) {
				scene.add( result.scene );
			},
			// Function called when download progresses
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},
			// Function called when download errors
			function ( xhr ) {
				console.log( 'An error happened' );
			}
		);
