Data Structures
class	GeomAPI_ExtremaCurveSurface
	Describes functions for computing all the extrema between a curve and a surface. An ExtremaCurveSurface algorithm minimizes or maximizes the distance between a point on the curve and a point on the surface. Thus, it computes start and end points of perpendiculars common to the curve and the surface (an intersection point is not an extremum except where the curve and the surface are tangential at this point). Solutions consist of pairs of points, and an extremum is considered to be a segment joining the two points of a solution. An ExtremaCurveSurface object provides a framework for: defining the construction of the extrema, implementing the construction algorithm, and consulting the results. Warning In some cases, the nearest points between a curve and a surface do not correspond to one of the computed extrema. Instead, they may be given by: a point of a bounding curve of the surface and one of the following: its orthogonal projection on the curve, a limit point of the curve; or a limit point of the curve and its projection on the surface; or an intersection point between the curve and the surface.
