Interactive Visualization of Mixed Scalar and Vector Fiel

This paper describes an approach for interactive visualization of mixed scalar and vector fielda, in which vector icons are generated from pre-vozelized icon templates and volume-rendered together with the volumetric scalar data. This approach displays simultaneously the global structure of the scalar field land the detailed features of the vector field. Interactive visualization is achieved with incremental image update, by re-rendering only a small portion of the image wherever and whenever a change occurs. This technique supports a set of interactive visualization tools, including change of vector field visualization parameters, real-time animation of vector icons advected within the scalar field, a zooming lens, and a local probe.
