Represents the state of a given selection mode for a
Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes More...

Detailed Description
Represents the state of a given selection mode for a
Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes
- mode 0 : selection of a trihedron
- mode 1 : selection of the origin of the trihedron
- mode 2 : selection of the axes
- mode 3 : selection of the planes XOY, YOZ, XOZ when you activate one of modes 1 2 3 4 , you pick AIS objects of type:
- AIS_Point
- AIS_Axis (and information on the type of axis)
- AIS_Plane (and information on the type of plane). AIS_PlaneTrihedron offers 3 selection modes:
- mode 0 : selection of the whole trihedron
- mode 1 : selection of the origin of the trihedron
- mode 2 : selection of the axes - same remarks as for the Trihedron. AIS_Shape : 7 maximum selection modes, depending on the complexity of the shape :
- mode 0 : selection of the AIS_Shape
- mode 1 : selection of the vertices
- mode 2 : selection of the edges
- mode 3 : selection of the wires
- mode 4 : selection of the faces
- mode 5 : selection of the shells
- mode 6 : selection of the constituent solids.
