const Handle< Geom_Circle > &  theCircle,
const Standard_Boolean  theIsFilled = Standard_False,
const Standard_Integer  theNbPnts = 12 
)

Constructs the sensitive circle object defined by the owner theOwnerId, the circle theCircle, the boolean theIsFilled and the number of points theNbPnts.

Select3D_SensitiveCircle::Select3D_SensitiveCircle ( const Handle< SelectBasics_EntityOwner > &  theOwnerId,

const Standard_Real  theU1,
const Standard_Real  theU2,
const Standard_Boolean  theIsFilled = Standard_False,
const Standard_Integer  theNbPnts = 12 
)

Constructs the sensitive arc object defined by the owner theOwnerId, the circle theCircle, the parameters theU1 and theU2, the boolean theIsFilled and the number of points theNbPnts. theU1 and theU2 define the first and last points of the arc on theCircle.

const Handle< TColgp_HArray1OfPnt > &  thePnts3d,
const Standard_Boolean  theIsFilled = Standard_False 
)

Constructs the sensitive circle object defined by the owner theOwnerId, the array of triangles thePnts3d, and the boolean theIsFilled. thePnts3d is an array of consecutive triangles on the circle. The triangle i+1 lies on the intersection of the tangents to the circle of i and i+2. Note, that the first point of thePnts3d must be equal to the last point of thePnts3d.
