基于X3D不规则圆柱体构造算法研究与实现

目前,多边形表面模型是最常用的一种三维几何模型表示方法.然而这种复杂的三维几何模型经常超过了系统的处理能力,既占据大量的存储空间,也不利于互联网传输.针对这一缺陷,文章提供一种使用X3D的Indexed Triangle Strip Set节点构造不规则圆柱体模型的方法.不规则圆柱体采用层数及每一层半径表示方法,并结合曲面精度一同拟合3D几何面.此方法具有模型构建精度高的特点.

Research and Implementation of Irregular Cylinder Constructing Algorithm

At present, the polygonal surface model is the most commonly used method to represent the three-dimensional geometric model. The complex three-dimensional geometric model, however, usually overrides the processing capacity of systems, which not only occupies more storage space, hut also is difficult to he transmitted over the Internet. Aiming at solving this problem, the Indexed Triangle Strip Set node is applied to construct the irregular cylinder model. Layers and each layer radius are used to describe the irregular cylinder and combine with the precision of surface profile to simulate the three-dimensional model. The method has the characteristics of high precision of modeling.
