23package AIS

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