| 摘 要： | 在充分对比CAD模型和三角网格模型特性的基础上，针对分布式同步协同设计的实时性要求和网络环境，提出基于三角网格模型进行分布式同步协同设计，建立了系统框架。该系统以三角网格模型作为产品的3D表达形式，通过构建有效的多分辨率模型与增量传输机制，在客户机/服务器环境下，实现客户端驱动的产品3D模型的远程实时动态观察和特征参数的在线讨论与修改。该系统可跨平台支持多个异地设计端点的协同。

| Abstract: | Based on contrasting the characteristics of CAD models and triangular mesh models, a new system of distributed collaborative design is proposed based on triangular mesh models according to network conditions and the requirements for real-time manipulation in distributed concurrent collaborative design. The framework is also constructed. Using triangular mesh models as 3D representation of the products, we realize remote and dynamic viewing of 3D product models driven by client in real-time in a client/server architecture through constructing efficient multi-resolution models and progressive transmission. Also, we can consult and alter the feature parameters of the products on-line. The system can be operated regardless of design platform type. |
