A loader for loading a .obj resource.
The OBJ file format is a simple data-format
that represents 3D geometry in a human readable format as the position of each vertex, the UV position of
each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of
vertices, and texture vertices.
// instantiate a loader
const loader = new OBJLoader();
// load a resource
loader.load(
// resource URL
'models/monster.obj',
// called when resource is loaded
function ( object ) {
scene.add( object );
},
// 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' );
}
);

[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.
[page:String url] — A string containing the path/URL of the .obj file.
[page:Function onLoad] — (optional) A function to be called after the loading is successfully completed. The function receives the loaded [page:Object3D] as an argument.
[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The function receives a XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives error as an argument.
Begin loading from url and call onLoad with the parsed response content.
[page:String text] — The textual obj structure to parse.
Returns an [page:Object3D]. It contains the parsed meshes as [page:Mesh] and lines as [page:LineSegments].
All geometry is created as [page:BufferGeometry]. Default materials are created as [page:MeshPhongMaterial].
If an obj object or group uses multiple materials while declaring faces, geometry groups and an array of materials are used.
[page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator materials] - A MaterialCreator instance.
Sets materials loaded by MTLLoader or any other supplier of a [page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator].
