【摘要】 随着仿真技术、计算机技术与网络技术的发展，仿真过程变得更为直观、更宜理解，有更多的交互性和更高的逼真度。实时分布仿真平台下的可视化技术是仿真技术研究中的一项关键技术，具有理论意义和工程实用价值。 论文主要对实时分布仿真可视化的特点、三维建模、视景仿真和真实感图形的实时显示等技术进行了研究和实现。具体工作如下： 1．分析了实时分布仿真下可视化技术的特点和需求，提出在实时分布仿真环境下实现可视化的构想，确定了可行的软件开发环境； 2．研究了三维实体建模方法、视景建模的基本理论和基于MultiGenCreatorPro的几何建模方法，采用3DS MAX、MultiGenCreatorPro等专业建模工具弥补了单纯利用OpenGL的实例库构造复杂几何体的不足； 3．研究了基于OpenGL的三维模型数据的读取算法，实现了三维模型数据地读取和采用OpenGL的显示列表对模型的简化； 4．研究了真实感图形的相关理论和方法以及动态特殊效果的模拟算法，包括多幅透明火焰纹理连续叠加绘制的燃烧效果算法、导弹尾焰的强烈喷射效果算法等，并实现了导弹尾焰喷射效果的模拟； 5．结合军工领域的工程项目实现了实时分布仿真可视化软件的开发，提供了仿真实时数据的曲线显示、仪表显示、三维动态显示等功能。更多还原

【Abstract】 With the development of computer graphics and computer network, the process of simulation is became to more visual, more intelligible .more exchangeable and more vivid .The visualization technology in real-time and distributed simulation is a crucial technology, this study has theory significance and works utility value.This paper has researched mainly key technology in visualization, including the features of visualization of simulation in real-time and distributed environment, 3D modeling, scene simulation and the real-time display of real graphics, in detailed as follows:(1) It analyses the features and demands of visualization technology of simulation in real-time and distributed environment and gives the plan of realization, it has also defined a feasible software develop environment.(2) The 3D object modeling methods, the basic theory of scene modeling and the methods of geometry modeling in MultigenCreatorpro are studied systematically in this paper. Using the professional modeling tools remedied the deficiency caused by only using the instance storehouse of OpenGL when modeling complex object, such as 3DS MAX, MultiGenCreatorpro.(3) This paper studied the algorithm of reading 3D model data in OpenGL and has realized it. It has also realized simplify model with display list of OpenGL.(4) The paper studied some related theory and methods with real graphics. It has also researched the simulation algorithm of special effects, including multi-transparent fire texture algorithm, dispersion effect of trail of missile algorithm and simulated the later.(5) This paper has developed the visualization software of real-time and distributed simulation. The software gives thecurve-display, the meter-display, the 3D animated display of real-time data in simulation.更多还原
