Detailed Description

An interface between the services provided by any surface from the package Geom and those required of the surface by algorithms which use it. Creation of the loaded surface the surface is C1 by piece.

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.
