class Selection from SelectMgr inherits TShared from MMgt
|
|
|
|
---Purpose: 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.
