A method is given for the construction of tubular surface patches . These surfaces are built from a 3D directrix curve that is single-valued either in Cartesian or in cylindrical coordinates. Control points for defining the patch lie on certain directions the distribution of which is controlled by two knot vectors. The surface is evaluated following a B… (More)
