基于Creator的飞行视景三维模型数据库优化技术

根据飞行视景仿真中三维建模的特点和要求,利用Creator强大的可视化建模功能和模型数据库优化技术,从调整模型数据库层级结构、减少模型复杂度和减小模型文件尺寸等几个方面着手,创建飞行视景仿真中所必需的飞机/导弹、座舱仪表和地形等典型对象的三维模型,在模型的复杂度和逼真度之间进行平衡,通过某飞行模拟训练系统软件开发中三维模型优化前后运行性能参数的对比,表明了优化建模的必要性和该建模技术在普通PC平台上支持飞行视景实时仿真的可行性.

Technology of Optimization of 3D Model Database for Flight Visualization Based on Creator

According to the features and demands of 3D modeling in flight visual simulation, using the powerful modeling function of Creator and the technology of optimization of 3D model database, including adjusting hierarchical structure of database, reducing modeling complexity and cutting down model file size etc, some typical models required in flight visual simulation, such as planes/missiles, cockpit instruments and terrains were created, and they were well balanced in complexity against fidelity, and some contrastive performance parameters of a certain flight simulation training system indicate the necessity of optimization of model database and feasibility of flight visual simulation on PC platform using such modeling technology.
