<h1>[name]</h1>
<p class="desc">A loader for loading a <em>.pdb</em> resource.<br>
The <a href="http://en.wikipedia.org/wiki/Protein_Data_Bank_(file_format)">Protein Data Bank</a> file format is a textual file describing the three-dimensional structures of molecules.
</p>
<h2>Example</h2>
<code>
// instantiate a loader
var loader = new THREE.PDBLoader();
// load a PDB resource
loader.load(
// resource URL
'models/molecules/caffeine.pdb',
// called when the resource is loaded
function ( pdb ) {
var geometryAtoms = pdb.geometryAtoms;
var geometryBonds = pdb.geometryBonds;
var json = pdb.json;
console.log( 'This molecule has ' + json.atoms.length + ' atoms' );
},
// 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' );
}
);
</code>

<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:null 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>.pdb</em> file.<br />
[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives the object having the following properties. [page:BufferGeometry geometryAtoms], [page:BufferGeometry geometryBonds] and the [page:Object JSON] structure.<br />
[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the 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 the error as an argument.<br />
</p>
<p>
Begin loading from url and call onLoad with the parsed response content.
</p>
<h3>[method:Object parse]( [param:String text] )</h3>
<p>
[page:String text] — The textual <em>pdb</em> structure to parse.
</p>
<p>
Parse a <em>pdb</em> text and return a <em>JSON</em> structure.<br />
