88 | //! Application Interactive Services provide the means to create links between an application GUI viewer and |
89 | //! the packages which are used to manage selection and presentation. |
90 | //! The tools AIS defined in order to do this include different sorts of entities: |
91 | //! both the selectable viewable objects themselves and the context and attribute managers to define their selection and display. |
92 | //! To orient the user as he works in a modeling environment, views and selections must be comprehensible. |
93 | //! There must be several different sorts of selectable and viewable object defined. |
94 | //! These must also be interactive, that is, connecting graphic representation and the underlying reference geometry. |
95 | //! These entities are called Interactive Objects, and are divided into four types: |
42cf5bc1 |
96 | //! - the Datum |
97 | //! - the Relation |
98 | //! - the Object |
99 | //! - None. |
8c088c52 |
100 | //! The Datum groups together the construction elements such as lines, circles, points, trihedra, plane trihedra, planes and axes. |
101 | //! The Relation is made up of constraints on one or more interactive shapes and the corresponding reference geometry. |
102 | //! For example, you might want to constrain two edges in a parallel relation. |
103 | //! This contraint is considered as an object in its own right, and is shown as a sensitive primitive. |
104 | //! This takes the graphic form of a perpendicular arrow marked with the || symbol and lying between the two edges. |
105 | //! The Object type includes topological shapes, and connections between shapes. |
106 | //! None, in order not to eliminate the object, tells the application to look further until it finds an object definition in its generation which is accepted. |
107 | //! Inside these categories, you have the possibility of an additional characterization by means of a signature. |
108 | //! The signature provides an index to the further characterization. |
109 | //! By default, the Interactive Object has a None type and a signature of 0 (equivalent to None.) |
110 | //! If you want to give a particular type and signature to your interactive object, you must redefine the two virtual methods: Type and Signature. |
111 | //! In the C++ inheritance structure of the package, each class representing a specific Interactive Object inherits AIS_InteractiveObject. |
112 | //! Among these inheriting classes, AIS_Relation functions as the abstract mother class for tinheriting classes defining display of specific relational constraints and types of dimension. |
113 | //! Some of these include: |
114 | //! - display of constraints based on relations of symmetry, tangency, parallelism and concentricity |
115 | //! - display of dimensions for angles, offsets, diameters, radii and chamfers. |
116 | //! No viewer can show everything at once with any coherence or clarity. |
117 | //! Views must be managed carefully both sequentially and at any given instant. |
118 | //! Another function of the view is that of a context to carry out design in. |
119 | //! The design changes are applied to the objects in the view and then extended to the underlying reference geometry by a solver. |
120 | //! To make sense of this complicated visual data, several display and selection tools are required. |
121 | //! To facilitate management, each object and each construction element has a selection priority. |
122 | //! There are also means to modify the default priority. |
123 | //! To define an environment of dynamic detection, you can use standard filter classes or create your own. |
124 | //! A filter questions the owner of the sensitive primitive to determine if it has the the desired qualities. |
125 | //! If it answers positively, it is kept. If not, it is rejected. |
42cf5bc1 |
126 | //! The standard filters supplied in AIS include: |
8c088c52 |
127 | //! - AIS_AttributeFilter |
128 | //! - AIS_SignatureFilter |
129 | //! - AIS_TypeFilter. |
130 | //! A set of functions allows you to choose the interactive objects which you want to act on, the selection modes which you want to activate. |
131 | //! An interactive object can have a certain number of graphic attributes which are specific to it, such as visualization mode, color, and material. |
132 | //! By the same token, the interactive context has a set of graphic attributes, the Drawer which is valid by default for the objects it controls. |
133 | //! When an interactive object is visualized, the required graphic attributes are first taken from the object's own Drawer if one exists, or from the context drawer for the others. |
