一种基于优先级的VRML文件优化技术

A PRIORITY-BASED VRML FILE OPTIMISATION TECHNIQUE

针对VRML文件描述的复杂场景模型数据信息量巨大,不利于网络传输与浏览的问题,提出一种基于优先级的VRML文件优化技术PBOT,并从相关度和价值两个方面综合考虑了点优先级的选取原则,在保证虚拟可视化显示质量的前提下,对该类数据进行优化处理。仿真实验结果表明PBOT可有效地提高数据传输效率,减轻网络链路压力。

In light of the problems of VRML file that the complicated scene model it depicted has huge data information and is inconvenient for network transmission and subscriber browse, we propose a priority-based optimisation technique for VRML file （PBOT）, and take into consideration comprehensively the selection principle of node priority from two aspects of correlation and value. While the virtual visualised display quality is ensured, the optimised processing on the data of such kind can be done. Simulation experimental results indicate that the PBOT can effectively imorove data transmission efficiency and alleviate the oressure of the network link.
