| 摘 要： | 本文在分析圆弧型过渡曲面的基础上,提出具有一阶连续性(C~1)的Bezier曲面来代替圆弧型曲面,采用旋转扫描方式求取相应的数据,获得光滑圆顺的过渡曲面,响应速度比园弧型的快将近一倍。理论上和实践上表明,它是一种简单快速实用的作图方法。

| Abstract: | On the basis of analysing the arc-type transition surface, this paper proposes to use Bezier surface with the first order continnity (C~1) to substitute for the arc-type surface,and use rotational scau mode to find out the corresponding data.A fair and smooth transition surface is thus obtained. The respond speed is nearly twice as fast as that of the arc-type. It has been proved both theoretically and practically to be a simple, fast and feasible method for drawing. |
