Detailed Description

Root class for 3D curves manipulated by handles, on which geometric algorithms work. An adapted curve is an interface between the services provided by a curve and those required of the curve by algorithms which use it. Two derived concrete classes are provided:

GeomAdaptor_HCurve for a curve from the Geom package
Adaptor3d_HCurveOnSurface for a curve lying on a surface from the Geom package.
