基于Java和MySQL的虚拟现实动态场景构建方法

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JavaEAI编程接口，并结合JDBC数据库驱动技术，实现了基于Java Applet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。

Research of Structuring VR Dynamic Scenes Based on Java and MySQL

The virtual reality modeling language (VRML),as the standard of describing the web three-dimension virtual scenes,is already applied to the visual simulation relevant research of every profession and trade extensively.But VRML and X3D (the new standard of VRML) are not very perfect in construction of the dynamic scene and acquisition of the real-time information of the scene objects.Through setting up the MySQL database which stored the geometrical property parameter of virtual scene objects,EAI programming interface was exploited which was offered by VRML language and based on Java Language,and combined with JDBC database technology to realize virtual reality dynamic scenes real-time structure effectively based on Java Applet through getting data from MySQL scene database of geometry information,and the scene objects could be connected with the records of attribute information database.Finally,the visual simulation application instance of hydroelectric project concrete dam build course was given.
