// Class : ModelPool
|
|
// Description : 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.
