多项式曲面逼近 polynomial surface approximation
Moreover,the curve and surface subdivision occurs in 3D object rendering, surface approximation,wireframe displaying, finite element analysis and computing surface intersections,and so on. Therefor, it is important significance to study a practical, steady and efficient algorithm to disperse curves and surfaces.
