Volume Rendering and Clipping for Air Pollution Visualization

In this paper, we present a novel and practical approach of volume rendering and clipping method 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, and 3D scene walkthrough is implemented in our system. We achieve expected experimental results and our research could benefit environment monitoring and many other applications associated with pollution visualization.
