<h1>[name]</h1>
<p class="desc">A loader for loading a <em>.obj</em> resource.<br />
The <a href="https://en.wikipedia.org/wiki/Wavefront_.obj_file">OBJ file format</a> 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.
</p>
<h2>Examples</h2>
<code>
// instantiate the loader
let objLoader2Parallel = new OBJLoader2Parallel();
// define where to attach the data
let local = new THREE.Object3D();
// function called on successful completion of parsing
function callbackOnLoad( object3d, message ) {
local.add( object3d );
}
// load a resource from provided URL in parallel to Main
objLoader2Parallel.load( 'models/obj/walt/WaltHead.obj', callbackOnLoad, null, null, null );
</code>
[example:webgl_loader_obj2_options] - Example for multiple use-cases (parse and load, sync (see [page:OBJLoader2]) or in parallel to main)<br>
<h2>Constructor</h2>
<h3>[name]( [param:LoadingManager manager] )</h3>
<p>
[page:LoadingManager manager] - The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].<br>
</p>
<p>
Creates a new [name]. Use it to load OBJ data from files or to parse OBJ data from arraybuffer.
It extends [page:OBJLoader2] with the capability to run the parser in a web worker.
</p>
<h2>Properties</h2>
<p>See the base [page:OBJLoader2] class for common properties.</p>
<h2>Methods</h2>
<p>See the base [page:OBJLoader2] class for common methods. </p>
<h3>[method:Object3D parse]</h3>
<p>See [page:OBJLoader2.parse].<br>
The callback [page:OBJLoader2.setCallbackOnLoad OBJLoader2.onLoad] needs to be set to be able to receive the content if used in parallel mode.
Fallback is possible via [page:OBJLoader2Parallel.setExecuteParallel].
</p>
<h3>[method:null load]</h3>
<p>See [page:OBJLoader2.load].</p>
<h3>[method:OBJLoader2Parallel setExecuteParallel] ( [param:boolean executeParallel] )</h3>
<p>
[page:boolean executeParallel] - True or False
</p>
<p>
Execution of parse in parallel via Worker is default, but synchronous [page:OBJLoader2] parsing can be enforced via false here.
</p>
<h3>[method:OBJLoader2Parallel setPreferJsmWorker] ( [param:boolean preferJsmWorker] )</h3>
<p>
[page:boolean preferJsmWorker] - True or False
</p>
<p>
Set whether jsm modules in workers should be used. This requires browser support which is currently only experimental.
</p>
<h3>[method:WorkerExecutionSupport getWorkerExecutionSupport] ()</h3>
<p>
Allow to get hold of [page:WorkerExecutionSupport] for configuration purposes.
</p>
<h3>[method:CodeBuilderInstructions buildWorkerCode] ()</h3>
<p>
Provide instructions on what is to be contained in the worker.
