The VisAD Java class library is for interactive and collaborative visualization and analysis of numerical data.

The use of pure Java and Java RMI for platform independence and to support data sharing and real-time collaboration among geographically distributed users. Support for distributed computing is integrated at the lowest levels of the system.

A general mathematical data model that can be adapted to virtually any numerical data, that supports data sharing among different users, different data sources and different scientific disciplines, and that provides transparent access to data independent of storage format and location (i.e., memory, disk or remote). Initially supported file formats include FITS, netCDF, HDF-EOS (via native library), Vis5D (via native library), GIF and JPEG.

A general display model that supports interactive 3-D, data fusion, multiple data views, direct manipulation, collaboration, and virtual reality. Data analysis and computation integrated with visualization to support computational steering and other complex interaction modes.
