摘要
针对基于瘦客户端结构的协同特征造型系统需要在服务器和客户端之间持续地传输庞大的数据模型,网络代价很高,提出一种基于细胞元模型的增量编辑方法。在服务器端对细胞元模型进行动态分割,识别并提取出一个很小变化的细胞元模型(CCM),然后传输到客户端并嵌入到编辑前的细胞元模型中。由于客户端向服务器发送的是造型指令和参数,而服务器反馈回客户端的是一个很小的变化的细胞元模型,从而降低了网络负荷,提高了更新效率。
The collaborative feature modeling systems, which used thin clients, require repeated transferring huge data models between server and clients, so it needed heavy bandwidth. This paper introduced a scheme for the incremental editing for cellular model, dynamically segmented the cellular model, Identified and extracted a small changed cellular model(CCM) in the server site, then transferred the CCM to the client site and embedded in the pre-edit cellular model. Because modeling operations and parameters were transmitted from the clients to the server and a very small changed cellular model was sent back, the network load was decreased, and the efficiency of update was improved.
