Description

Visit is a new open-source visualization application that was developed under the Department of Energy's Accelerated Strategic Computing Initiative (ASCI).  VisIt is intended to support the wide variety of computational science and engineering analysis tools used within the ASCI program, and to be deployed on a variety of desktop and supercomputer platforms.  Therefore, VisIt's features and capabilities read more like a high-performance production-grade commercial visualization application than a free software package available for download from the web.

Features

VisIt supports a wide variety of visualization capabilities and data formats, including data representations (e.g., SILO, EXODUS) that include support for parallel processing applications.  Although VisIt is free software, its feature list includes most of the high-end capabilities of commercial tools (e.g., support for scalable rendering of contours and isosurfaces), as well as powerful features that extend VisIt's core capabilities, e.g., scripting in the Python language, extensibility through plug-in interfaces, etc.  VisIt's UCD (Unstructured Cell Data) data type permits flexible integration of VisIt's features with existing finite-element analysis tools, and its built-in capabilities for visualization and data manipulation are sufficiently broad so as to support virtually all aspects of computational engineering, including the fluid mechanics analyses required for modeling tsunamis.
