[page:Loader] →

[name]

A loader for loading a [page:BufferGeometry]. This uses the [page:FileLoader] internally for loading files.

Code Example


		// instantiate a loader
		const loader = new THREE.BufferGeometryLoader();

		// load a resource
		loader.load(
			// resource URL
			'models/json/pressure.json',

			// onLoad callback
			function ( geometry ) {
				const material = new THREE.MeshLambertMaterial( { color: 0xF5F5F5 } );
				const object = new THREE.Mesh( geometry, material );
				scene.add( object );
			},

			// onProgress callback
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},

			// onError callback
			function ( err ) {
				console.log( 'An error happened' );
			}
		);

Constructor

[name]( [param: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

See the base [page:Loader] class for common properties.

Methods

See the base [page:Loader] class for common methods.

[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )

[page:String url] — the path or URL to the file. This can also be a [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].d
[page:Function onLoad] — Will be called when load completes. The argument will be the loaded [page:BufferGeometry].
[page:Function onProgress] (optional) — Will be called while load progresses. The argument will be the ProgressEvent instance, which contains .[page:Boolean lengthComputable], .[page:Integer total] and .[page:Integer loaded]. If the server does not set the Content-Length header; .[page:Integer total] will be 0.
[page:Function onError] (optional) — Will be called when load errors.

Begin loading from url and call onLoad with the parsed response content.

[method:BufferGeometry parse]( [param:Object json] )

[page:Object json] — The `JSON` structure to parse.

Parse a `JSON` structure and return a [page:BufferGeometry].
