On the first display request, this structure is created by calling the appropriate algorithm and retaining this framework for further display. //! This abstract framework is inherited in Application Interactive Services (AIS), notably by AIS_InteractiveObject. //! Consequently, 3D presentation should be handled by the relevant daughter classes and their member functions in AIS. //! This is particularly true in the creation of new interactive objects. //! //! Key interface methods to be implemented by every Selectable Object: //! - AcceptDisplayMode() accepting display modes implemented by this object; //! - Compute() computing presentation for the given display mode index. //! //! Warning! Methods managing standard attributes (SetColor(), SetWidth(), SetMaterial()) have different meaning for objects of different type (or no meaning at all). //! Sub-classes might override these methods to modify Prs3d_Drawer or class properties providing a convenient short-cut depending on application needs. //!
