In my last post, I looked at some unusual options for visualizing subsurface phenomena. The subsurface bodies in that example, which might represent pollutant plumes or ore bodies, were generated as isosurfaces from fractal volumes.
Another volume modeling visualization area of application is analyzing atmospheric data. A few years back we animated some model data representing the devastating Hurricane Katrina. Here's a frame from that animation that I've regenerated at higher resolution:

Model data is courtesy of Jian-Wen Bao of the National Oceanic and Atmospheric Administration (NOAA). The gray atmospheric "body" shows the 25 m/s isosurface generated from model output for a time slice on Aug 29, 2005. The core of the high wind area engulfs New Orleans, LA, with the well-known tragic results. You can view a small-sized version of the animation in the "Volume Modeling" section of our animations page.
