AIS_OffsetDimension Class Reference

A framework to display dimensions of offsets.
The relation between the offset and the basis shape
is indicated. This relation is displayed with arrows and
text. The text gives the dsitance between the offset
and the basis shape.

Standard_EXPORT AIS_OffsetDimension (const TopoDS_Shape &FistShape, const TopoDS_Shape &SecondShape, const Standard_Real aVal, const TCollection_ExtendedString &aText)
 Constructs the offset display object defined by the
first shape aFShape, the second shape aSShape, the
dimension aVal, and the text aText.
.
virtual Standard_EXPORT 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 AIS_KindOfDimension KindOfDimension () const
 Indicates that the dimension we are concerned with is an offset.
.
virtual Standard_Boolean IsMovable () const
 Returns true if the offset datum is movable.
.
void SetRelativePos (const gp_Trsf &aTrsf)
 Sets a transformation aTrsf for presentation and
selection to a relative position.
.

Private Member Functions

virtual Standard_EXPORT void Compute (const Handle(PrsMgr_PresentationManager3d)&aPresentationManager, const Handle(Prs3d_Presentation)&aPresentation, const Standard_Integer aMode=0)
 Calculates the 3D 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.
.
Standard_EXPORT 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.
.
Standard_EXPORT 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 Standard_EXPORT void ComputeSelection (const Handle(SelectMgr_Selection)&aSelection, const Standard_Integer aMode)
 Recovers and calculates any sensitive primitive,
aSelection, available in Shape mode, specified by
aMode. As a rule, these are sensitive faces.
This method is defined as virtual. This enables you to
implement it in the creation of a new class of AIS
Interactive Object. You need to do this and in so
doing, redefine this method, if you create a class
which enriches the list of signatures and types.
