Research on virtual interactive library management system based on VRML

为研究图书馆管理系统的三维可视化和信息交互功能,文中构建了基于VRML虚拟现实技术的可视化的数字图书信息管理系统。首先对图书馆外观和功能进行考察分析,分析关键建模技术、渲染技术和碰撞检测技术方案,结合VRML技术对图书馆外观、大厅、借阅室建立了可视化三维模型;其次,采用3D MAX软件进行人物虚拟,通过Viewpoint节点实现了对视觉控制点的方向控制,借助传感器TimeSensor节点和位置插补器PositionInterpolator,实现动画漫游交互;最后,集合Java技术为图书馆的信息管理交互设计接口,并引入向量空间模型提高了信息查询的精确程度。文中的三维可视化图书馆信息和交互系统为类似的信息管理技术提供了一定参考和借鉴。

In order to study the 3D visualization and information interaction function of library mana-gement system,a digital book information management system is constructed in this paper based on VRML virtual reality technology.Firstly,the appearance and function of the library is analyzed in this paper and the key technology of modeling,rendering and collision detection is put forward.Combined with VRML technology,the visual 3D model of library appearance,hall and reading room is established.Second,with production softwares 3D MAX software for virtual characters,through the Viewpoint node realizes the visual control point in the direction of the control,with the help of a sensor node Time Sensor and location interpolation Position Interpolator and implement animation roaming interaction.Finally,set Java technology designs interactive interface for library information management,and introduces vector space model to improve the accuracy of information query.
