deferred class SensitiveEntity from Select3D inherits
|
|
SensitiveEntity from SelectBasics
|
|
|
|
---Purpose: Abstract framework to define 3D sensitive entities.
|
|
-- As the selection process uses the principle of a
|
|
-- projection of 3D shapes onto a 2D view where
|
|
-- nearness to a rectangle determines whether a shape
|
|
-- is picked or not, all 3D shapes need to be converted
|
|
-- into 2D ones in order to be selected.

NeedsConversion(me) returns Boolean is redefined static;
|
|
---Level: Public
|
|
---Purpose: Returns true if this framework needs conversion.

---C++: inline

Is3D(me) returns Boolean from Standard is redefined static;

---Purpose: Returns true if this framework provides 3D information.

Project (me:mutable;aProjector : Projector from Select3D) is deferred;
|
|
---Level: Public
|
|
---Purpose: In classes inheriting this framework, you must
|
|
-- redefine this function in order to get a sensitive 2D
|
|
-- rectangle from a 3D entity. This rectangle is the
|
|
-- sensitive zone which makes the 3D entity selectable.

---Level: Public
|
|
---Purpose: Returns the max number of sensitive areas returned

|
|
-- Else on must redefine this method.
|
|
|
|
|
|
GetConnected(me:mutable;aLocation: Location from TopLoc)
|
|
returns SensitiveEntity from Select3D is virtual;
|
|
---Purpose: Originally this method intended to return sensitive
|
|
-- entity with new location aLocation, but currently sensitive
|
|
-- entities do not hold a location, instead HasLocation() and
|
|
-- Location() methods call corresponding entity owner's methods.
|
|
-- Thus all entities returned by GetConnected() share the same
|
|
-- location propagated from corresponding selectable object.
|
|
-- You must redefine this function for any type of
|
|
-- sensitive entity which can accept another connected
|
|
-- sensitive entity.//can be connected to another sensitive entity.

|

---Purpose: Matches the box defined by the coordinates Xmin,

|
-- Ymin, Xmax, Ymax with the entity found at that point
|
|
-- within the tolerance aTol.
|
|
-- Xmin, YMin define the minimum point in the lower left
|
|
-- hand corner of the box, and XMax, YMax define the
|
|
-- maximum point in the upper right hand corner of the box.
|
|
-- You must redefine this function for every inheriting entity.
|
|
-- You will have to call this framework inside the redefined function.

---Category: Location of sensitive entities...
|
|
-- Default implementations of HasLocation() and Location() rely on

-- SetLocation() and ResetLocation() do nothing by default.
