【摘要】 科学技术的发展，使得人们要求接收信息的方式更加直观、更易理解、有更多的交互性和更高的逼真度。这种信息处理方法是建立在一个多维化的信息空间中，一个定性与定量相结合、感性认识与理性认识相结合的综合集成环境中，虚拟现实技术将是支撑这个多维信息空间的关键技术。 本文主要研究了基于虚拟现实技术的航空、航天三维动画设计实现过程。在VC++环境中，利用虚拟现实的原理设计开发了发动机试车三维动画系统和空对地导弹三维动画系统。深入地研究了基于几何、基于图象、基于外部模型输入等三维图像建模思想和方法，成功地建立了三维场景。重点研究了一维、二维纹理贴图以及不规则光栅图像在虚拟场景中的应用，并取得了满意的视觉效果。开发设计了友好的交互式功能和操作界面，提高了系统的可观、可控性，增强了实用性。 本文开发的航空发动机试车三维动画系统为航空发动机试车领域和科研、教学演示提供了逼真的工作环境。开发的空对地导弹三维动画系统为空对地导弹的战术应用、协调作战提供了直观的观察平台。更多还原

【Abstract】 As development of science, people need the way of receiving information to be more visual, more comprehensible, and more interactive with fidelity. This information processing is based on cyberspace. This is a comprehensive integrated environment that combines qualitative analysis with quantitative analysis and combines the perceptual and the rational cognition. Virtual Reality will be the key technology in the cyberspace.This paper research that process of designing three-dimensional animated of aerospace based on Virtual Reality. Using the theory of Virtual Reality we develop the system of engine testing and the system of air-to-ground missile (AGM) in VC++. Studying the thought and method of three-dimensional image deeply based on geometry, extra model inputting as well as image etc. Building three-dimensional scene successfully. Researching texture mapping and anomalistic raster image be used in Virtual reality. Moreover getting good visual impression. Developing friendly interactive function and operation panel, it improves visual perception control and adds practical applicability of this system.Three-dimensional animated design of aviation engine testing provides a real environment for aviation engine testing field and study scientific research, teaching demonstration. Air-to-ground missile (AGM) provides intuitionistic observation plat for AGM tactical application and coordinated operation.更多还原
