摘要
在现有计算机图形学技术和数字声音模拟技术的基础上,分析了声、光在传播特性上的差异,使用改进的辐射度算法,提出在室内具有屏障遮挡的声波-衍射波的处理方法,真实地模拟了室内声传播的衰变特性。
Based on computer graphics and data acoustic simulation technology,the difference of propagation characteristics between sound and light is analyzed in this paper. Furthermore,with update radiosity algorithm,a diffraction processing method of sound wave under barrier environment is provided,and the weakening characteristics of sound wave in room are simulated really.
