摘要
在视景仿真中能够精确地控制虚拟场景中的对象模型是增强系统交互性的重要手段。该文分析了虚拟场景中三维模型对象和视点的控制方法，重点介绍了基于3D输入设备的对象控制方法。在详细分析3D输入设备SpaceBall4000的特点、工作原理和应用技术的基础上，在VC++－Vega－Creator一体化建模仿真开发环境中基于该3D输入设备实现了虚拟场景中三维模型对象和视点的6自由度精确控制，提供了应用三维输入设备控制虚拟场景的一种方法。
In visual simulation, how to control model objects in virtual space is the important means to enhance the interactive capabilities of system. The paper analyzes the control methods of 3D model objects and viewpoint in virtual space, especially emphasizes the control method based on 3D input devices. The paper labors the characteristics, principles and applying technologies of SpaceBall4000, a 3D input device, and implements the control method of 3D objects and viewpoint up to six degrees of freedom with pinpoint decision using the programming platform of VC++, Vega and Creator based on the 3D device, so presents a kind of method to control virtual space with 3D input devices.
