摘要
通过对已有入口技术的分析和总结,探讨了入口技术的发展现状、研究方向和研究趋势。将入口分为传统入口和任意入口两种类别,分析了不同类别的入口算法的处理方法和存在的优劣,然后对两类入口的各自特色进行了比较和总结,最后指出未来仍然需要重点研究的若干关键问题。
Portal technique is one of the significant components of large-scale indoor scenes.With the deepening of the research,the portal can be used not only visibility,but also can be used in many other aspects,including simulating mirror and as the connector between different scenes and so on.Firstly,it made that of analyzing and summarizing of related portal algorithms,discussing the development statues,research ways and direction of portal.Secondly,it discoursed upon the classified portals to conventional portals and arbitrary portals,analyzing the relative algorithms in different categories,and comparing the characteristics with each other.Finally,some key research issues that need further study in near future are pointed out.
