Mathematical Objects

Mathematical, or Pure Geometric Objects, are dynamically created objects, which are not part of the model. but rather used for geometric calculations. Mathematical Objects do not normally implement IEntity_DG interface.

Mathematical Objects can be created with a query similar to: IObjectGenerator_DG > Create<IPlane_DG>() > IPlane_DG

Examples of Mathematical Objects are: Frame, Splined 3D Curves, and simpler objects like Oriented Box, Plane and arcs

Although Mathematical Objects are not part of the model, in many cases they still can be rendered in the scene using IScene_DG.CreatePresentationEntity(). IDraw_DG is another way of "drawing into the model" for simple objects.
