Abstract: Key techniques of visualization model system based on military simulation entities are discussed. According to the categories of this visualization model, the modeling methods and general frame of visualization model system are established. Model rules on LOD, grades of damage, texture and grouping are constituted, and the fuzzy synthetically evaluation method is used to choose the level of discrete LOD. The hierarchical architecture of the visualization model is also proposed. The techniques involving spacial database and relational database are synthesized to build the data storage framework, and the algorithm of reconstructing model is introduced. Test results show this system is effective.

Key words: military simulation entities, visualization model, model rule, level architecture, data structure

摘要： 介绍军事仿真实体可视化模型系统的关键技术，提出军事仿真实体可视化模型的分类，确定各类模型的建模方法，并依此设计系统的总体架构。制定模型的层次细节、损伤分级、纹理和分组规则，并采用模糊综合评判方法确定离散LOD等级。提出可视化模型的层次体系结构，采用空间数据库和关系数据库相结合的方法进行模型数据存储，并给出基于数据库的三维模型重构算法。测试结果表明了该系统的有效性。
