The Implementation of 3D Scene Walkthrough in Air Pollution Visualization

We present a practical and novel approach to implement 3D scene walkthrough for air pollution visualization. This approach includes volume rendering and clipping methods, which are used to visualize large-scale air pollution data. A new viewpoint-based volume clipping method is used while rendering, which is fast and more interactive than previous methods. We achieved expected experimental results and our research could benefit environment monitoring and many other applications associated with pollution visualization.
