The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ModelRegistry` class. ## Example ```typescript import { ModelRegistry } from 'hytopia'; const modelRegistry = ModelRegistry.instance; const boundingBox = modelRegistry.getBoundingBox('models/player.gltf'); ``` ## Properties
