19 ---Purpose: Application Interactive Services provide the means to
20 -- create links between an application GUI viewer and
21 -- the packages which are used to manage selection
22 -- and presentation. The tools AIS defined in order to
23 -- do this include different sorts of entities: both the
24 -- selectable viewable objects themselves and the
25 -- context and attribute managers to define their
26 -- selection and display.
27 -- To orient the user as he works in a modeling
28 -- environment, views and selections must be
29 -- comprehensible. There must be several different sorts
30 -- of selectable and viewable object defined. These must
31 -- also be interactive, that is, connecting graphic
32 -- representation and the underlying reference
33 -- geometry. These entities are called Interactive
34 -- Objects, and are divided into four types:
35 -- - the Datum
36 -- - the Relation
37 -- - the Object
38 -- - None.
39 -- The Datum groups together the construction elements
40 -- such as lines, circles, points, trihedra, plane trihedra,
41 -- planes and axes.
42 -- The Relation is made up of constraints on one or
43 -- more interactive shapes and the corresponding
44 -- reference geometry. For example, you might want to
45 -- constrain two edges in a parallel relation. This
46 -- contraint is considered as an object in its own right,
47 -- and is shown as a sensitive primitive. This takes the
48 -- graphic form of a perpendicular arrow marked with
49 -- the || symbol and lying between the two edges.
50 -- The Object type includes topological shapes, and
51 -- connections between shapes.
52 -- None, in order not to eliminate the object, tells the
53 -- application to look further until it finds an object
54 -- definition in its generation which is accepted.
55 -- Inside these categories, you have the possibility
56 -- of an additional characterization by means of a
57 -- signature. The signature provides an index to the
58 -- further characterization. By default, the Interactive
59 -- Object has a None type and a signature of 0
60 -- (equivalent to None.) If you want to give a particular
61 -- type and signature to your interactive object, you must
62 -- redefine the two virtual methods: Type and Signature.
63 -- In the C++ inheritance structure of the package, each
64 -- class representing a specific Interactive Object
65 -- inherits AIS_InteractiveObject. Among these
66 -- inheriting classes, AIS_Relation functions as the
67 -- abstract mother class for tinheriting classes defining
68 -- display of specific relational constraints and types of
69 -- dimension. Some of these include:
70 -- - display of constraints based on relations of
71 -- symmetry, tangency, parallelism and concentricity
72 -- - display of dimensions for angles, offsets,
73 -- diameters, radii and chamfers.
74 -- No viewer can show everything at once with any
75 -- coherence or clarity. Views must be managed
76 -- carefully both sequentially and at any given instant.
77 -- Another function of the view is that of a context to
78 -- carry out design in. The design changes are applied
79 -- to the objects in the view and then extended to the
80 -- underlying reference geometry by a solver. To make
81 -- sense of this complicated visual data, several display
82 -- and selection tools are required. To facilitate
83 -- management, each object and each construction
84 -- element has a selection priority. There are also
85 -- means to modify the default priority.
86 -- To define an environment of dynamic detection, you
87 -- can use standard filter classes or create your own. A
88 -- filter questions the owner of the sensitive primitive in
89 -- local context to determine if it has the the desired
90 -- qualities. If it answers positively, it is kept. If not, it is rejected.
91 -- The standard filters supplied in AIS include:
92 -- AIS_AttributeFilter
93 -- AIS_SignatureFilter
94 -- AIS_TypeFilter.
95 -- Only the type filter can be used in the default
96 -- operating mode, the neutral point. The others can
97 -- only be used in open local contexts.
98 -- Neutral point and local context constitute the two
99 -- operating modes of the central entity which pilots
100 -- visualizations and selections, the Interactive Context.
101 -- It is linked to a main viewer and if you like, a trash bin
102 -- viewer as well.
103 -- The neutral point, which is the default mode, allows
104 -- you to easily visualize and select interactive objects
105 -- which have been loaded into the context. Opening
106 -- local contexts allows you to prepare and use a
107 -- temporary selection environment without disturbing
108 -- the neutral point. A set of functions allows you to
109 -- choose the interactive objects which you want to act
110 -- on, the selection modes which you want to activate,
111 -- and the temporary visualizations which you will
112 -- execute. When the operation is finished, you close the
113 -- current local context and return to the state in which
114 -- you were before opening it (neutral point or previous
115 -- local context).
116 -- An interactive object can have a certain number of
117 -- graphic attributes which are specific to it, such as
118 -- visualization mode, color, and material. By the same
119 -- token, the interactive context has a set of graphic
120 -- attributes, the Drawer which is valid by default for the
121 -- objects it controls. When an interactive object is
122 -- visualized, the required graphic attributes are first
123 -- taken from the object's own Drawer if one exists, or
124 -- from the context drawer for the others.
