摘　　要：三维噪声地图作为三维GIS的重要组成部分,已经广泛应用到交通规划和城市建设等领域。随着计算机图形学技术及虚拟现实技术的不断发展,三维开源引擎在大范围城市场景三维建模的成熟应用为实时渲染技术的研究提供可行性。本文基于OGRE三维开源引擎,通过计算建筑模型将预测结果实时生成纹理贴图渲染在三维噪声地图上,直观清晰地展示城市区域交通噪声的污染程度和分布情况。As an important part of 3D GIS,3D noise map has been widely used in transportation planning and urban construction.With the continuous development of computer graphics technology and virtual reality technology,the mature application of 3D open source engine on 3D modeling of large-scale urban scenes provides feasibility for the research of real-time rendering technology.Based on the OGRE 3D open source engine,this paper simulates the building model and generates the texture map in real time to render the 3D noise map to visually and clearly show the pollution degree and distribution of traffic noise in the urban area.
