Adaptor3d_Surface Class Reference

Root class for surfaces on which geometric algorithms work.
An adapted surface is an interface between the
services provided by a surface and those required of
the surface by algorithms which use it.
A derived concrete class is provided:
GeomAdaptor_Surface for a surface from the Geom package.
The Surface class describes the standard behaviour
of a surface for generic algorithms.

The Surface can be decomposed in intervals of any
continuity in U and V using the method
NbIntervals. A current interval can be set. Most
of the methods apply to the current interval.
Warning: All the methods are virtual and implemented with a
raise to allow to redefined only the methods realy
used.
