面向用户的产品虚拟模型协同讨论环境的实现

针对基于Web的虚拟设计中面向用户的协同交流的需要，着重介绍了一种对产品虚拟模型进行协同讨论的系统。提出对产品的VRML模型进行节点定义的预处理方法，通过VRML Automation接口实现了虚拟模型协同设计和浏览的新方法，并设计了相关的控制策略。结合矢量化的电子图板和文字及语音通信实现了产品虚拟模型的实时评注和讨论。

Implementation of Customer Oriented Collaborative Discuss Environment for Virtual Product Modeling

For the purpose of customer oriented communication in the Web-based virtual design, a collaborative discussion environment for the virtual entity of the product is introduced. A new approach to preprocess the VRML model and collaboratively operate the VRML model is proposed. The control strategy for the multi-users is designed and realized. With 2D electronic whiteboard and literal chat, real-time voice communication simultaneously, virtual entity of the product can be discussed on the Web.
