Data Structures
class	Convert_ElementarySurfaceToBSplineSurface
	Root class for algorithms which convert an elementary surface (cylinder, cone, sphere or torus) into a BSpline surface (CylinderToBSplineSurface, ConeToBSplineSurface, SphereToBSplineSurface, TorusToBSplineSurface). These algorithms all work on elementary surfaces from the gp package and compute all the data needed to construct a BSpline surface equivalent to the cylinder, cone, sphere or torus. This data consists of the following: degrees in the u and v parametric directions, periodic characteristics in the u and v parametric directions, a poles table with associated weights, a knots table (for the u and v parametric directions) with associated multiplicities. The abstract class ElementarySurfaceToBSplineSurface provides a framework for storing and consulting this computed data. This data may then be used to construct a Geom_BSplineSurface surface, for example. All those classes define algorithmes to convert an ElementarySurface into a B-spline surface. This abstract class implements the methods to get the geometric representation of the B-spline surface. The B-spline representation is computed at the creation time in the sub classes. The B-spline surface is defined with its degree in the parametric U and V directions, its control points (Poles), its weights, its knots and their multiplicity.
