Abstract:  VRML is the main file format transmitting the 3D model on the Internet,but the complicated scene model contains a large amount of information. Though traditional VRML file has already adopted the compression of a certain form to deal with, the file is still relatively huge. A binary compression algorithm based on VRML file was proposed in this paper. The files were compressed with binary compression, which was suitable for transmitting in the network without causing the congestion of network. At the same time, the data information did not influence visual display quality after compressing.

摘要：  VRML已经成为互联网上传输三维模型的主要文件格式。对于复杂场景模型具有数据信息量大的特点,尽管传统的VRML文件已采用了某种形式的压缩处理,但其文件仍旧相对庞大。因此,文章提出针对VRML文件的二进制压缩编码技术,对这些数据进行压缩处理,使之大小适合在网络中传输,同时压缩后的数据信息不影响虚拟可视化的显示质量。
