摘　　要：研究了可视化仿真建模的理论、技术与方法,实现了渤海海峡跨海通道的仿真建模与可视化表达。MultiGen Creator是一套将多边形建模、矢量建模和地形生成集成在一个软件包中的手动建模工具。论述了MultiGen Creator模型的OpenFlight数据层次结构,对仿真建模的关键技术及算法进行了理论分析,主要包括拉伸、放样、纹理映射及层次细节模型等技术。随后对渤海海峡跨海通道形式及系统组成进行了比较分析,并基于Creator仿真建模平台,给出了跨海通道仿真建模流程,建立了海底隧道模型数据库的树状结构。最终实现了海底铁路隧道、公路隧道及悬浮隧道等不同跨海通道形式的可视化仿真,使工程各部位的基本信息及空间上的逻辑关系得到较好的体现。Theories, technologies and methods of visualization simulation modeling were studied. Simulation models of the trans-sea channels of Bohai strait were visually represented. MuhiGen Creator is a set of modeling tool which integrating polygon modeling, vectorgraph modeling and topographty creating into a software package. The Open- Flight data hierarchy structure in MtthiGen Creator was introduced first. Then the key technologies of simulation mod- eling and its algorithm were theoretically analyzed including the technologies of Wall algorithm, Loft algorithm, texture mapping, operation of LOD decimation. Subsequently, the styles of the trans-sea channels of Bohai strait and its system constitution were comparatively analyzed. Based on the platform of Creator, modeling flow diagram of trans-sea channels was given and the tree-like hierarchy of undersea channel model was created. Finally simulation models of different channels styles, including undersea railway tunnels, highway tunnels and suspension tunnels, were implemented. By means of the visualization models, basic information and spatial logical relationships of the engineering were well described.
