输入设备在Vega应用中的接入方法研究

Vega软件环境默认的输人设备为鼠标，以其控制实体或视点的运动不够形象直观，需要将特定的输人设备应用到视景仿真系统中。在分析了Vega结构和工作原理的基础上，通过设计自定义的运动模式以及创建管理输人设备的Vega类实例，将特定的输人设备接人到基于Vega的视景仿真应用中。结果表明，该方法操作简单灵活，感觉直观，有效地改善了仿真实验效果。

Study on the Method for Introducing Input Device in Vega Application

The default input device in Vega software environment is mouse. It's not realistic and intuitional to control the motion of object or observer by mouse. Other types of input devices need to be applied to scene simulation system. In this paper, the structure and work theory of Vega are analyzed. Then a kind of motion model is designed and an instance of Vega class is created to manage the device, through which the specified device is introduced in the scene simulation application based on Vega. The results show that the operation is easy and flexible, the experimenter has an intuitional sense and the simulation effects are improved.
