虚拟战场环境中的声音仿真应用研究及实现

在作战实验室这样的大型人－环分布式仿真应用中，环境的逼真度以及由此产生的成员沉浸感，是仿真可信度的先决条件之一。研究虚拟战场环境中的声音合成是提高环境逼真度的重要途径。该文从应用角度对虚拟战场环境下声音的仿真有关问题作了较系统的探讨，并采用Ｍｉｃｒｏｓｏｆｔ的ＤｉｅｃｔＳｏｕｎｄ ＳＤＫ编程实现。

Sound Simulation Study and Implementation under the Circumstance of Virtual Battlefield

In such a large scale man in the loop DIS application as warfare simulation,the fidelity of the Virtual Environment and Immersion of the members is key factor to achive a high reliabity of the experemental result. To study the Virtual Sound Generation(VSG) is one important way to improve the fidelity of Synthetic Environment.This paper presents an systematic analysis on VSG from applied aspects and then give an on trial implementation while programming with Microsoft DirectSound SDK.
