摘要
本文在分析张量积有理B样条蒙皮面曲面方法不足的基础上,给出了用截面外形设计原理构造有理蒙皮曲面、回转曲面及扫掠曲面的方法,并提出了对G^1连续的有理曲线进行重新参数化使其达到C^1连续的方法。文中的实例表明用该方法能够产生满足设计要求的参数曲面。
Several problems which exist in the rational B-spline skinning surface method are presented,
and a theory for crosssectional design of rational Bézier surface for CAD/CAM is described.The
surface construction methods given include skinning,sweeping and swinging.A method to repa-
rameterize a G^1 rational curve to obtain a C^1 curve is given also.
