Transformation Persistence definition.
Transformation Persistence defines a mutable Local Coordinate system which depends on camera position, so that visual appearance of the object becomes partially immutable while camera moves. Object visually preserves particular property such as size, placement, rotation or their combination.
Graphic3d_TMF_ZoomPers, Graphic3d_TMF_RotatePers and Graphic3d_TMF_ZoomRotatePers define Local Coordinate system having origin in specified anchor point defined in World Coordinate system, while Graphic3d_TMF_TriedronPers and Graphic3d_TMF_2d define origin as 2D offset from screen corner in pixels.
Graphic3d_TMF_2d, Graphic3d_TMF_TriedronPers and Graphic3d_TMF_ZoomPers defines Local Coordinate system where length units are pixels. Beware that Graphic3d_RenderingParams::ResolutionRatio() will be ignored! For other Persistence flags, normal (world) length units will apply.
WARNING: Graphic3d_TMF_None is not permitted for defining instance of this class - NULL handle should be used for this purpose!
