基于X3D/JAVA的大型虚拟场景的可视化构建

Visualization of Large Virtual Scene based on X3D/JAVA

根据X3D的XML的编码特性,设计出基于X3D的大型虚拟场景的可视化构建方法。以虚拟植物园的构建为例,将复杂场景分解成可操作的、可视化的、具有统一功能接口X3D的物体原型。在JAVA平台中,通过SAI(Scene Access Interface)对X3D原型进行可视化操作和交互,实时同步跟踪原型参数,进而通过DOM组件来实现X3D文件的序列化生成,从而快捷、有效地生成X3D三维场景。

According to the coding characteristics of X3D's XML,a visual construction method for large virtual scene based on X3D is designed.Taking the construction of virtual botanical garden as an example,the complex scene is decomposed into an object prototype that is operable,visualized and with unified functional interface X3D.In the JAVA platform,the visualization of the operation and interaction were attributed to X3D prototypes through SAI,and the real-time synchronization tracking was monitored on parameters of the prototype.Then,the sequence of generation X3D file was formed through the DOM components to quickly and effectively generate X3D scene.
