机场视景模型参数化建模方法研究

随着计算机虚拟现实和视景仿真技术的发展与完善,用于提高视景的逼真度和视觉效果的技术在飞行模拟机视景仿真中已得到广泛的应用。但是,基于Multigen Creator等3D建模软件构建机场模型的缺点日益凸显:人工收集机场数据、手工绘制机场拓扑图的建模方法耗时、费力、效率低、缺乏灵活性和可复用性。针对这些问题,结合机场路网结构的特点,将参数化的思想引入到机场路网三维建模过程中,提出了一种基于交通拓扑约束的机场路网参数化三维建模方法,设计并实现了基于该方法的用于视景的机场路网模型参数化建模系统。该系统已成功应用到机场模型建模工作中,建模速度较之传统方法有了显著的提高,而且制作出来的模型可以复用,系统在稳定性、可扩展性和可移植性方面表现出色,并具有很强的真实感和沉浸感。

Research on Parametric Modeling of Airport Virtual Scenes

With the development and improvement of computer virtual reality and visual simulation technology,improving the fidelity of the visual and visual effects technology in the flight simulator has been widely used.But,airport modeling based on the Multigen Creator and other 3D modeling software has increasingly obvious shortcomings: collecting the airport data manually,hand-painting airport topology.As for those problems,this paper introduces a parameter modeling method into airport traffic network 3D modeling,and a new 3D modeling method is proposed,which constraints the relation described by traffic network topology.The system based on this modeling technology has been developed.And the airport network 3D model generated by the system has strong sense of reality and easy-to-be-maintain.
