void	Perform (const gp_Pnt &theP, const Standard_Real theU0, const Standard_Real theV0, const Standard_Boolean isDistanceCriteria=Standard_False)
	Calculates the extrema between the point and the surface using a close point. The close point is defined by the parameter values theU0 and theV0. Type of the algorithm depends on the isDistanceCriteria flag. If flag value is false - normal projection criteria will be used. If flag value is true - distance criteria will be used.

	Returns the value of the extremum square distance.

const Extrema_POnSurf &	Point () const
	Returns the point of the extremum distance.

static

Returns True if UV point theU0, theV0 is point of local minimum of square distance between point theP and points theS(U, V), U, V are in small area around theU0, theV0.

◆ Perform()

void Extrema_GenLocateExtPS::Perform	(	const gp_Pnt &	theP,
		const Standard_Real	theU0,
		const Standard_Real	theV0,
		const Standard_Boolean	isDistanceCriteria = Standard_False )

Calculates the extrema between the point and the surface using a close point. The close point is defined by the parameter values theU0 and theV0. Type of the algorithm depends on the isDistanceCriteria flag. If flag value is false - normal projection criteria will be used. If flag value is true - distance criteria will be used.

◆ Point()

const Extrema_POnSurf & Extrema_GenLocateExtPS::Point ( ) const

Returns the point of the extremum distance.

◆ SquareDistance()

Standard_Real Extrema_GenLocateExtPS::SquareDistance ( ) const

Returns the value of the extremum square distance.
