说明：  虚拟现实建模语言（VRML）作为描述网络三维虚拟场景的标准，已广泛应用于各行业的 可视化仿真相关研究，然而 VRML 以及其新标准 X3D 在动态场景的构建和场景对象的实时信息获 取方面很不完善，通过建立用于存储虚拟场景物体的几何特征参数的 MySQL 数据库，利用 VRML 语言提供的Java EAI编程接口，并结合JDBC数据库驱动技术，实现了基于JavaApplet的从MySQL 场景几何信息数据库到虚拟现实动态场景的实时快速构建，以及场景对象到对应属性信息数据库记 录的连接，最后给出了水电工程混凝土大坝浇筑过程可视化仿真的应用实例。
(Virtual Reality Modeling Language (VRML) as described in the standard network three-dimensional virtual scene, has been widely used in various industries visual simulation studies, however, as well as its new standard VRML X3D scenes in a dynamic and scene objects to build real-time information access areas are imperfect, through the establishment of a virtual scene objects used to store the geometric parameters of the MySQL database, using the VRML language programming interfaces provided by Java EAI, combined with JDBC database driver technology, based on the realization JavaApplet scene geometry information from the MySQL database to the virtual reality quickly build dynamic scenes in real time, as well as to the corresponding scene object attribute information database records connected Finally pouring concrete dam hydropower project process visualization simulation application examples.)
