<p class="desc">A loader for loading a <em>.prwm</em> resource.<br />
|
|
Packed Raw WebGL Model is an open-source binary file format for nD geometries specifically designed for
|
|
JavaScript and WebGL with a strong focus on fast parsing (from 1ms to 0.1ms in Chrome 59
|
|
on a MBP Late 2013). The parsing of PRWM file is especially fast when the endianness of the file is
|
|
the same as the endianness of the client platform. More information
|
|
on this <a href="https://github.com/kchapelier/PRWM">here</a>.

<h2>代码示例</h2>
|
|
|
|
<code>
|
|
// instantiate a loader
|
|
const loader = new PRWMLoader();
|
|
|
|
// load a resource
|
|
loader.load(
|
|
// resource URL
|
|
'models/nefertiti.le.prwm',
|
|
// called when resource is loaded
|
|
function ( bufferGeometry ) {
|
|
|
|
const object = new THREE.Mesh( bufferGeometry, new THREE.MeshNormalMaterial() );
|
|
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' );
|
|
|
|
}
|
|
);

<h2>例子</h2>

<p>

|
[example:webgl_loader_prwm]
|
|
</p>
|
|
|
|
<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].
|
|
</p>
|
|
<p>
|
|
Creates a new [name].
|
|
</p>
|
|
|
|
<h2>Properties</h2>
|
|
<p>See the base [page:Loader] class for common properties.</p>
|
|
|
|
<h2>Methods</h2>
|
|
<p>See the base [page:Loader] class for common methods.</p>
|
|
|
|
<h3>[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
|
<p>
|
|
[page:String url] — A string containing the path/URL of the <em>.prwm</em> file. Any <em>*</em> character in the URL will be automatically replaced by <em>le</em> or <em>be</em> depending on the platform endianness.<br />
|
|
[page:Function onLoad] — (optional) A function to be called after the loading is successfully completed. The function receives the loaded [page:BufferGeometry] as an argument.<br />
|
|
[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.<br />
|
|
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives error as an argument.<br />
|
|
</p>
|
|
<p>
|
|
Begin loading from url and call onLoad with the parsed response content.
|
|
</p>
|
|
|
|
<h3>[method:BufferGeometry parse]( [param:ArrayBuffer arrayBuffer] )</h3>
|
|
<p>
|
|
[page:ArrayBuffer arrayBuffer] — ArrayBuffer containing the <em>prwm</em> data.
|
|
</p>
|
|
<p>
|
|
Parse a <em>prwm</em> file passed as an ArrayBuffer and directly return an instance of [page:BufferGeometry].
|
|
</p>
|
|
|
|
<h3>PRWMLoader.isBigEndianPlatform( )</h3>
|
|
|
|
<p>
|
|
Return true if the endianness of the platform is Big Endian, false otherwise.
|
|
</p>
