Detailed Description

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.

Polynomial coefficients of BSpline surfaces used for their evaluation are cached for better performance. Therefore these evaluations are not thread-safe and parallel evaluations need to be prevented.
