[name]

A loader for loading a .pdb resource.
The Protein Data Bank file format is a textual file describing the three-dimensional structures of molecules.

Example


		// 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' );

			}
		);

Constructor

[name]( [param:LoadingManager manager] )

[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].

Creates a new [name].

Properties

See the base [page:Loader] class for common properties.

Methods

See the base [page:Loader] class for common methods.

[method:null load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )

[page:String url] — A string containing the path/URL of the .pdb file.
[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.
[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.
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.

Begin loading from url and call onLoad with the parsed response content.

[method:Object parse]( [param:String text] )

[page:String text] — The textual pdb structure to parse.

Parse a pdb text and return a JSON structure.
