| Abstract: | NURBS is the only mathematic method about geometric definition of industrial product in the STEP international standard. The significance of rational interpolation of NURBS curve is obvious. But people often adopt non-rational interpolation. The study of rational interpolation is very little. An exact solution for rational interpolation and a method for the creation of complete NURBS curve are given in this paper. |

| Keywords: | NURBS curve weight control point |
