摘要
根据作战仿真可视化的需求,为提高仿真实体三维模型存储、复用和使用效率,分析了作战仿真实体模型数据管理的优缺点,采用空间逻辑描述和空间逻辑变换,提出了一种新的实体三维模型数据结构和存储方法,设计了三维实体模型快速重构的几何层次与数据结构体系,建立了实体三维模型全局层、集合层、单元层、表面层、顶点层和空间逻辑层,并给出了模型重构的算法。结合某型坦克三维实体模型的重构应用实例,实现了实体各部件的空间逻辑标准化,为作战单元实体仿真三维模型重构提供了一种可行的技术途径。
According to the requirement of visualization in military simulation system, to improve the efficiency on data storage, reuse and utility of the 3D modeling, the merits and demerits of military simulation entities management were analysed, data storage structure and method for 3D model were constructed by the spatial logic description and transform, and a new method about geometry and data structure for entity fast reconstruction was designed,which comprises six layers as the panorama layer, the aggregation layer, the object layer, the surface layer, the vertex layer and the spatial logic layer. Taking an example about tank model, the restructing algorithm for reconstructing 3D model was introduced, which makes the entities combination normatively and provides a feasible technical approach for construction, management and utility.
