ModelPool
from panda3d.core import ModelPool
- class ModelPool
Bases:
DTOOL_SUPER_BASEThis 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.
