// Class : ModelPool
|
|
// Description : This is the preferred interface for loading models.
|
|
// It 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.
|
|
//
|
|
// This does not presently support asynchronous loading,
|
|
// although it wouldn't be *too* difficult to add.
