<h1>[name]</h1>
<div class="desc">
A loader for loading a <em>.pdb</em> resource.
<br /><br />
The <a href="http://en.wikipedia.org/wiki/Protein_Data_Bank_(file_format)">Protein Data Bank file format</a> is a textual file format describing the three-dimensional structures of molecules.
</div>
<h2>Constructor</h2>
<h3>[name]( [page:LoadingManager manager] )</h3>
<div>
[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
</div>
<div>
Creates a new [name].
</div>
<h2>Properties</h2>
<h2>Methods</h2>
<h3>[method:null load]( [page:String url], [page:Function onLoad], [page:Function onProgress], [page:Function onError] )</h3>
<div>
[page:String url] — required. URL to the <em>.pdb</em> file<br />
[page:Function onLoad] — Will be called when load completes. The arguments will be an [page:Geometry geometryAtoms], [page:Geometry geometryBonds] and the [page:Object JSON] structure.<br />
[page:Function onProgress] — Will be called while load progresses. The argument will be the XmlHttpRequest instance, that contain .[page:Integer total] and .[page:Integer loaded] bytes.<br />
[page:Function onError] — Will be called when load errors.<br />
</div>
<div>
Begin loading from url and call onLoad with the parsed response content.
</div>
<h3>[method:Object parsePDB]( [page:String text] )</h3>
<div>
[page:String text] — The textual <em>pdb</em> structure to parse.
</div>
<div>
Parse a <em>pdb</em> text and return a <em>JSON</em> structure.<br />
</div>
<h3>[method:null createModel]( [page:Object json], [page:Function callback] )</h3>
<div>
[page:Object json] — The <em>(JSON) pdb</em> structure to parse.<br />
[page:Function callback] — Will be called when parse completes, with three arguments: [page:Geometry geometryAtoms], [page:Geometry geometryBonds] and the original [page:Object json].<br />
</div>
<div>
Parse a <em>(JSON) pdb</em> structure and return two [page:Geometry]: one for atoms, one for bonds.<br />
</div>
<h2>Example</h2>
<code>
// instantiate a loader
var loader = new THREE.PDBLoader();
// load a PDB resource
loader.load(
// resource URL
'models/molecules/caffeine.pdb',
// Function when resource is loaded
function ( geometryAtoms, geometryBonds, json ) {
console.log( 'This molecule has ' + json.atoms.length + ' atoms' );
},
// Function called when download progresses
function ( xhr ) {
console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
},
// Function called when download errors
function ( xhr ) {
console.log( 'An error happened' );
}
);
</code>
