【摘要】 虚拟现实技术是近些年高速发展的一种新技术,它利用计算机软件构造出一个三维空间的虚拟世界。其中VRML(即虚拟现实建模语言)更是发展迅速,VRML是一种用于建立真实世界场景的模型或人们虚拟的三维世界场景的建模语言,利用计算机虚拟现实技术辅助教学日益发展。本文结合VRML及JavaScript技术,研究了晶体空间点阵旋转对称性的虚拟建模方法,给出了便于操作的具有复杂交互功能的程序软件,VRML技术在教育、教学领域具有广阔的应用前景。更多还原

【Abstract】 Virtual reality is a new technology developed in recent years; it uses computer software to construct a three-dimensional virtual world. Computer assisted teaching technology by virtual reality is growing,and VRML( Virtual Reality Modeling Language) is developing rapidly. VRML is a modeling language used in construction real-world scenario model or virtual three-dimensional scene of the world. It briefly describes the modeling methods of VRML in showing rotational symmetry of crystal space lattice combining VRML and Java Script technology,and an easy operated program software with complex interactive function is developed. VRML technology has broad application prospects in the field of education and teaching.更多还原
