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