+class SurfaceOfRevolution from Adaptor3d inherits Surface from Adaptor3d
+
+
+ --- Purpose : This class defines a complete surface of revolution.
+ -- The surface is obtained by rotating a curve a complete revolution
+ -- about an axis. The curve and the axis must be in the same plane.
+ -- If the curve and the axis are not in the same plane it is always
+ -- possible to be in the previous case after a cylindrical projection
+ -- of the curve in a referenced plane.
+ -- For a complete surface of revolution the parametric range is
+ -- 0 <= U <= 2*PI. --
+ -- The parametric range for V is defined with the revolved curve.
+ -- The origin of the U parametrization is given by the position
+ -- of the revolved curve (reference). The direction of the revolution
+ -- axis defines the positive sense of rotation (trigonometric sense)
+ -- corresponding to the increasing of the parametric value U.
+ -- The derivatives are always defined for the u direction.
+ -- For the v direction the definition of the derivatives depends on
+ -- the degree of continuity of the referenced curve.
