摘要 在初始控制网格确定的情况下,生成的曲面形状惟一确定,最终的物体造型也随之确定,不具有可调性。通过在曲面细分过程中引入一个参数,给出一种新的细分曲面构造的算法,使得所得的细分曲面的表达度可控。调节一个参数值,可以得到一系列的细分曲面。最后给出了曲面设计的实例,表明这种算法简单、有效。 The shape of the subdivision surface and the final object model are determined by the initial control mesh given, it's unadjustable. An adjustable subdivision surface scheme based on arbitrary topological meshes to design adjustable subdivision surfaces using a control parameters is presented. Kinds of subdivision surfaces is created by changing the parameter. Some examples of the subdivision surfaces given demonstrate the simpleness, flexibility and efficiency of the algorithm.
