摘要
军事训练是虚拟现实技术应用最早,也是目前最成熟和最广泛的领域之一。虚拟环境中的建模与仿真一直是计算机图形学研究中的一个热门课题,也是本课题所研究的关键技术。从近期发生的几场高技术局部战争来看,空袭和反空袭作战将是我军的一种重要的作战模式,在我国自行高炮在反空袭作战中有着举足轻重的作用。论文《某高炮火控系统三维动画仿真的研究与实现》正是为了适应未来作战的需要,采用面向对象的设计方法,实现某高炮火控系统仿真平台的视觉模拟。
本文研究了基于OpenGL下的某高炮火控系统三维动画仿真,在VC++6.0环境中创建了虚拟仿真平台,仿真了在雷达已经捕获目标后,自行高炮对空中目标进行瞄准、跟踪和射击的过程;实现了虚拟自行高炮车体的地形匹配,进一步提高了仿真系统的真实感和沉浸感;初步解决了虚拟环境中的碰撞检测问题,通过用户手动操作虚拟高炮的转向来绕开障碍物,提高了仿真系统的交互性;实现了随动系统的仿真,为操炮手的仿真训练提供了软件接口;对三维动画的流畅性进行了分析,实现了基于三角形折叠的网格简化与特征保持的模型简化算法,提高了仿真平台的运行速度,改进了三维动画的流畅性。
Military training is one of the first application of virtual reality technology, but also one of the most mature and wide range of areas. Modeling and simulation has been a hot topic in computer graphics in the virtual environment, which is also the key technology stuyed by the subject. As far as recent several high technology local wars concerned, wars with air attack and against air attack will be an important campaign pattern of our army in the future. Anti-aircraft artillery plays an important role in the anti-air raid operations. In order to adapt to the needs of future operations, the paper, "the Research and Implementation of three-dimensional animated simulation of Anti-aircraft artillery's fire control system", achieve a certain anti-aircraft fire control system simulation platform of visual simulation using object-oriented design methods.
In this paper author analyze and study the three-dimensional animated simulation of Anti-aircraft artillery's fire control system Based on OpenGL, creates a virtual simulation platform in VC++6.0 environment, Simulates the process of aiming at, tracking on and shooting targets in the air, implements the terrain match of vehicle of anti-aircraft artillery, improve the virtual reality system and the realistic sense of immersion further, Preliminary solves problem of the collision detection in the virtual environment, improves the system's interactive through the manual operation to the virtual anti-aircraft artillery to avoid obstacles, realizes the simulation of dynamic system, provides software interface for the gunners' simulation training, Analyzes the fluency of 3-D animation, realizes the model simplification algorithm based on the folded triangle mesh simplification and maintain the characteristics of model, Improves 3-D animation of fluency.
