GeomAdaptor_SurfaceOfRevolution Class Reference

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. More...
