| Abstract: | As the special example of rational B-spline curves,rational Bezier curves are becoming increasingly widespread.According to the theory of Bezier curve,the joining between adjacent rational Bezier curves is studied; meanwhile,the G~1 and G~2 continuity conditions of two random degree adjacent rational Bezier curves are given. |

| Keywords: | rational Bezier curves G~2 continuity characteristic polygon control vertex weight |
