Visual3 - A Software Environment for Flow Visualization

A graphics environment has been developed for the visualization of three-dimensional engineering and scientific data. Unlike existing packages, it can handle a wide variety of structured and unstructured grids, and deals with generic scalar and vector data, making it suitable for a wide range of physical applications. An important feature of the package is the ability to view unsteady data in either post-processing or co-processing modes. Another unique aspect of Visual3 is the dimensional windowing approach coupled with cursor mapping which allows efficient pointing in 3D space. There is also a strong emphasis on a wide variety of `probes' allowing the user to interactively investigate the computational data. In that this is a discussion of an interactive visualization environment, these notes cannot be considered complete without a live demonstration of Visual3.
