## Public Member Functions

Standard_EXPORT | AIS_Point (const Handle(Geom_Point)&aComponent)
| Initializes the point aComponent from which the point datum will be built. .
virtual Standard_Integer | Signature () const
| Returns index 1, the default index for a point. .
virtual AIS_KindOfInteractive | Type () const
| Indicates that a point is a datum. .
Standard_EXPORT Handle_Geom_Point | Component ()
| Returns the component specified in SetComponent. .
Standard_EXPORT void | SetComponent (const Handle(Geom_Point)&aComponent)
| Constructs an instance of the point aComponent. .
Standard_EXPORT Standard_Boolean | AcceptDisplayMode (const Standard_Integer aMode) const
| Returns true if the display mode selected is valid for point datums. .
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 !!!
Standard_EXPORT void | SetColor (const Quantity_NameOfColor aColor)
| Allows you to provide settings for the cp;pr aColor. .
Standard_EXPORT void | SetColor (const Quantity_Color &aColor)
Standard_EXPORT void | UnsetColor ()
| Allows you to remove color settings. .
Standard_EXPORT void | SetMarker (const Aspect_TypeOfMarker aType)
| Allows you to provide settings for a marker. These include - type of marker, - marker color, - scale factor. .
Standard_EXPORT void | UnsetMarker ()
| Removes the marker settings. .
Standard_Boolean | HasMarker () const
| Returns true if the point datum has a marker. .
Standard_EXPORT TopoDS_Vertex | Vertex () const
| Converts a point into a vertex. .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const

## Private Member Functions

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. .
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.
