A loader for loading a `.pdb` resource.
The Protein Data Bank file format is a textual file describing the three-dimensional structures of molecules.
// instantiate a loader
const loader = new PDBLoader();
// load a PDB resource
loader.load(
// resource URL
'models/pdb/caffeine.pdb',
// called when the resource is loaded
function ( pdb ) {
const geometryAtoms = pdb.geometryAtoms;
const geometryBonds = pdb.geometryBonds;
const 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' );
}
);

[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
Creates a new [name].
See the base [page:Loader] class for common properties.
See the base [page:Loader] class for common methods.
[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. If the server does not set the Content-Length header; .[page:Integer total] will be 0.
[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.
[page:String text] — The textual `pdb` structure to parse.
Parse a `pdb` text and return a `JSON` structure.
