[page:Loader] →


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' ); } );

[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].


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


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] — Will be called while load progresses. 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.
[page:Function onError] — 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].
