【摘要】 提出了一种新的基于客户端/服务器架构的可用于室内环境虚拟漫游的实现方案。该方法首先根据面片的属性和用户提供的阈值,将场景中的面片进行剖分,建立面片之间的链接,并构造场景面片的 q-j 面片链接表,然后对场景进行预绘制,并把绘制的结果保存在全景图中,漫游过程中利用全景图合成新视点的视图。存储全景图所需要的数据结构不大,漫游中只需要传递少量面片,适用于网上虚拟漫游系统。更多还原

【Abstract】 A new scheme based on Client/Server frame for indoor environment virtual walkthrough is presented in this paper. The proposed method first constructs a hierarchical q-j polygon patches linking map of all the patches by adaptively subdividing patches into subpatches according to the patch抯 attribute and a user-supplied error bound. After that, the environment is rendered using a light tracing algorithm and the result is saved in a panoramic map. The panoramic map is used to synthesize the view at novel viewpoint during walkthrough process. The size of the data structures required by storing panoramic map is not much large, and only a sparse set of patches is needed to be transferred over network, so this method is well suitable for web-based virtual walkthrough system.更多还原
