49 //! A framework to manage presentation and selection of shapes.
50 //! AIS_Shape is the interactive object which is used the
51 //! most by applications. There are standard functions
52 //! available which allow you to prepare selection
53 //! operations on the constituent elements of shapes -
54 //! vertices, edges, faces etc - in an open local context.
55 //! The selection modes specific to "Shape" type objects
56 //! are referred to as Standard Activation Mode. These
57 //! modes are only taken into account in open local
58 //! context and only act on Interactive Objects which
59 //! have redefined the virtual method
60 //! AcceptShapeDecomposition so that it returns true.
61 //! Several advanced functions are also available. These
62 //! include functions to manage deviation angle and
63 //! deviation coefficient - both HLR and non-HLR - of
64 //! an inheriting shape class. These services allow you to
65 //! select one type of shape interactive object for higher
66 //! precision drawing. When you do this, the
67 //! Prs3d_Drawer::IsOwn... functions corresponding to the
68 //! above deviation angle and coefficient functions return
69 //! true indicating that there is a local setting available
70 //! for the specific object.
