三维场景下水淹分析方法的研究与实现

Study and Implement for Flooding Analysis in 3D Scene

首先阐述了洪水淹没分析的实现原理,然后分析了利用静态"水位面"进行计算的水淹分析两种形式,即无源式水淹分析和有源式水淹分析。其中,针对无源式水淹分析,给出了其在三维场景下分析的实现步骤;针对有源式水淹分析,在总结分析现有算法的基础上,提出一种兼顾连通性和分析效率的"淹没区扩展法",并给出了该算法在三维场景下的实现步骤。

This paper elaborates the realization principle of flooding analysis, and then analyses the no source flood submergence and source flood submergence, these two forms using the "water level surface". For the no source flood submergence, it presents the implementation steps of the analysis in the 3D scene. For the source flood submergence, it summarizes the existing algorithms, and based on these algorithms, it proposes a method of "extending of submerged area" algorithm. The method is taking into account connectivity and analysis efficiency, and the implementation steps of the analysis in the 3D scene are presents in the end.
