◆ IsDone()

Standard_Boolean Extrema_GenLocateExtPS::IsDone ( ) const

Returns True if the distance is found.

◆ IsMinDist()

static Standard_Boolean Extrema_GenLocateExtPS::IsMinDist ( const gp_Pnt theP,
const Adaptor3d_Surface theS,
const Standard_Real  theU0,
const Standard_Real  theV0 
)
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.
