Adaptor2d_HCurve2d Class Referenceabstract

Root class for 2D 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. A derived specific class is provided: Geom2dAdaptor_HCurve for a curve from the Geom2d package. More...

Detailed Description

Root class for 2D 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. A derived specific class is provided: Geom2dAdaptor_HCurve for a curve from the Geom2d package.
