AIS_Point()

AIS_Point::AIS_Point

(

const occ::handle< Geom_Point > &

aComponent

)

Initializes the point aComponent from which the point datum will be built.

Member Function Documentation

AcceptDisplayMode()

bool AIS_Point::AcceptDisplayMode ( const int aMode ) const

overridevirtual

Returns true if the display mode selected is valid for point datums.

Reimplemented from PrsMgr_PresentableObject.

Component()

occ::handle< Geom_Point > AIS_Point::Component

(

)

Returns the component specified in SetComponent.

Compute()

void AIS_Point::Compute ( const occ::handle< PrsMgr_PresentationManager > & thePrsMgr, const occ::handle< Prs3d_Presentation > & thePrs, const int theMode )

overrideprotectedvirtual

Calculates the 3D view presentation for specified display mode. This is a key interface for implementing Presentable Object interface.

Parameters

thePrsMgr	presentation manager where presentation has been created
thePrs	presentation to fill
theMode	display mode to compute; can be any number accepted by AcceptDisplayMode() method
