基于VRML的三维几何体建模算法研究

Research of algorithm of modeling of 3D geometry shape based on VRML

由于虚拟现实建模语言(VRML)的繁杂性,用其直接构造三维几何体较为困难,我们根据VRML97规范中定制的几类三维几何体,分别予以算法实现,从而提高基于VRML创建三维虚拟场景的效率。本文主要讨论基于VRML进行三维几何体建模中的主要算法,最后展示了利用建模算法完成的一个三维场景建模实例。

Because of the complexity of virtual reality modeling language (VRML), it is difficult to construct 3D geometry shape with VRML directly. We create some basic algorithms for every 3D geometry shape based on VRML97 standard. So efficiency will be improved greatly. In this paper we discuss some essential algorithm of how to modeling 3D geometry shape based on VRML, finally, we show a modeling instance making use of the algorithm.
