deferred class SelectableObject from SelectMgr inherits PresentableObject from PrsMgr
|
|
|
|
---Purpose: A framework to supply the structure of the object to be
|
|
-- selected. At the first pick, this structure is created by
|
|
-- calling the appropriate algorithm and retaining this
|
|
-- framework for further picking.
|
|
-- This abstract framework is inherited in Application
|
|
-- Interactive Services (AIS), notably in AIS_InteractiveObject.
|
|
-- Consequently, 3D selection should be handled by the
|
|
-- relevant daughter classes and their member functions
|
|
-- in AIS. This is particularly true in the creation of new interactive objects.

---Purpose: Recovers and calculates any sensitive primitive,

|
-- aMode. As a rule, these are sensitive faces.
|
|
-- This method is defined as virtual. This enables you to

---Purpose: Empties all the selections in the SelectableObject
|
|
-- <update> parameter defines whether all object's

-- selections should be flagged for further update or not.
|
|
-- This improved method can be used to recompute an

---Purpose: If returns True, the old mechanism for highlighting

|
-- If all object presentations are removed, the layer ID will be set to

|
-- default value when computing presentation. The layers mechanism allows
