Detailed Description

[AI] Presenter class for managing 3D model (ROI) presentation and their relationship with entities in the world.

Inherits from MxVideoPresenter.

[AI] Handles the instantiation, configuration, and tickle logic of a 3D ROI (Render Object Instance) as used in LEGO Island. Supports parsing extra actions, streaming model data from resources, configuring textures, and linking ROIs to entities or placing them in the world. Can be configured for special texture handling via a static configuration. [AI]
