This paper describes three alternative volume rendering approaches to visualizing computational fluid dynamics (CFD) data. One new approach uses realistic volumetric gas rendering techniques to produce photo-realistic images and animationsfrom scalar CFD data. The second uses ray casting that is based on a simpler illuminationmodel and is mainly centered around a versatile new tool for the design of transfer functions. The third method employs a simple illumination model and rapid rendering mechanisms to provide efficient preview capabilities. These tools provide a large range of volume rendering capabilities to be used by the CFD explorer to render rapidly for navigation through the data, to emphasize data features (e.g., shock waves) with a specific transfer function, or to present a realistic rendition of the model. 1 Introduction This paper describes three alternative approaches for volumetric visualization of CFD data. One new approach uses a realistic surface and volumetric rend...
