[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 v3d.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'); } ); [example:webgl_loader_pdb]

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.

[method:PDBLoader setPath]([param:String path])

[page:String path] — Base path.

Set the base path for the file.
