/**
|
|
* This class unifies all references to the same filename, so that multiple
|
|
* attempts to load the same model will return the same pointer. Note that
|
|
* the default behavior is thus to make instances: use with caution. Use the
|
|
* copy_subgraph() method on Node (or use NodePath::copy_to) to make
|
|
* modifiable copies of the node.
|
|
*
|
|
* Unlike TexturePool, this class does not automatically resolve the model
|
|
* filenames before loading, so a relative path and an absolute path to the
|
|
* same model will appear to be different filenames.
|
|
*
|
|
* However, see the Loader class, which is now the preferred interface for
|
|
* loading models. The Loader class can resolve filenames, supports threaded
|
|
* loading, and can automatically consult the ModelPool, according to the
|
|
* supplied LoaderOptions.
