Discussion
Components are the basis for customizable file format and object graph support in Model I/O. By default, the MDLObject uses the MDLObjectContainerComponent and MDLTransformComponent protocols to model object hierarchies and spatial transforms: When you load an object graph from a MDLAsset instance, Model I/O creates container and transforms components to represent the object hierarchy and spatial relationships described in the asset file. However, you can also create custom components. For example, a custom component protocol could add support for an asset format that encodes gameplay-related information such as scripting triggers, or a custom class for the MDLObjectContainerComponent could implement other ways to store or traverse object hierarchies.
