摘要: 实现一种三维模型在网络中渐进传输的方法,该方法根据SmoothLOD模型编码的思想,设计了一个基于C/S的网络传输架构,从而实现在浏览过程中从一个点到复杂模型的平滑过渡效果,并且可以方便地实现三维模型在网络上平滑地增量传输。通过在数字博物馆系统的应用验证,算法实现了模型在网络上流式传输,有效地减少了数据传输的网络延迟。

Abstract: This paper proposes a progressive transmition of 3D model on network, designs a C/S network architecture for SmoothLOD transmition, realizes the effect of smooth transmition from a single point to the complex model when being browsed and conveniently implements the incremental transmission on network. As the application of digital museum project shows, the method can realize the streaming transmition of model on network and reduce the network delay of data transmition.
