AIS_MultipleConnectedInteractive Class Reference

Defines an Interactive Object by gathering together
several object presentations. This is done through a
list of interactive objects. These can also be
Connected objects. That way memory-costly
calculations of presentation are avoided.

 AIS_MultipleConnectedInteractive (const PrsMgr_TypeOfPresentation3d aTypeOfPresentation3d=PrsMgr_TOP_AllView)
 Initializes the Interactive Object with multiple
presentation connections. If aTypeOfPresentation3d
does not have the affectation PrsMgr_TOP_AllView,
it is projector dependent.

void Connect (const Handle< AIS_InteractiveObject > &anotherIObj)
 Add anotherIObj in the presentation of me

virtual AIS_KindOfInteractive Type () const
 Returns the kind of Interactive Object:

virtual Standard_Integer Signature () const
 Specifies additional characteristics of Interactive
Objects. A signature is, in fact, an index with integer
values assigned different properties.
This method is frequently used in conjuction with
Type to give a particular type and signature to an
Interactive Object. By default, the Interactive Object
has a None type and a signature of 0. Among the
datums, this signature is attributed to the shape
The remaining datums have the following default signatures:

Standard_Boolean HasConnection () const
 Returns true if the object is connected to others.

const AIS_SequenceOfInteractiveConnectedTo () const
 Returns the connection references of the previous
Interactive Objects in view.

void Disconnect (const Handle< AIS_InteractiveObject > &anotherIObj)
 Removes the connection anotherIObj to an entity.

void DisconnectAll ()
 Clears all the connections to objects.

virtual void Compute (const Handle< PrsMgr_PresentationManager2d > &aPresentationManager, const Handle< Graphic2d_GraphicObject > &aPresentation, const Standard_Integer aMode=0)
 Calculates the 2D view aPresentation and its
updates. The latter are managed by aPresentationManager.
aPresentableObject has the display mode aMode;
this has the default value of 0, that is, the wireframe display mode.
Note that this syntax is not used in AIS as that
package only concerns 3D display.

virtual void Compute (const Handle< Prs3d_Projector > &aProjector, const Handle< Geom_Transformation > &aTrsf, const Handle< Prs3d_Presentation > &aPresentation)
 computes the presentation according to a point of view
given by <aProjector>.
To be Used when the associated degenerated Presentations
have been transformed by <aTrsf> which is not a Pure
Translation. The HLR Prs can't be deducted automatically
WARNING :<aTrsf> must be applied
to the object to display before computation !!!

virtual void Compute (const Handle< Prs3d_Projector > &aProjector, const Handle< Prs3d_Presentation > &aPresentation)
 Calculates the 3D view aPresentation and its
updates. The latter are managed by
aPresentationManager. Each of the views in the
viewer and every modification such as rotation, for
example, entails recalculation.
It must be redefined to implement hidden line removal
for the object. The user never calls this method
himself. This is done via the InteractiveContext object
and is dependent on the point of view from which the
object is displayed.

  • Point signature 1
  • Axis signature 2
  • Trihedron signature 3
  • PlaneTrihedron signature 4
  • Line signature 5
  • Circle signature 6
  • Plane signature 7.

  • None
  • Datum
  • Relation
  • Object
    By default, the interactive object has a None type.
    Because specific shapes entail different behavior
    according to their sub-shapes, you may need to
    create a Local Context. This will allow you to
    specify the additional characteristics which you
    need to handle these shapes.
