// Class : Loader
|
|
// Description : A convenient class for loading models from disk, in
|
|
// bam or egg format (or any of a number of other
|
|
// formats implemented by a LoaderFileType, such as
|
|
// ptloader).
|
|
//
|
|
// This class supports synchronous as well as
|
|
// asynchronous loading. In asynchronous loading, the
|
|
// model is loaded in the background by a thread, and an
|
|
// event will be generated when the model is available.
|
|
// If threading is not available, the asynchronous
|
|
// loading interface may be used, but it loads
|
|
// synchronously.
