| | 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: More...
