IBM Visualization Data Explorer, a second generation visualization
appliation and toolkit, provides scientists and engineers the means of
applying advanced visualization techniques to gain insights from
simulations, observations, models and combinations of them.  The ability
to combine disparate data sets and perform correlative analysis gives
scientists and engineers a unique capability.  Data Explorer exmploys a
dataflow client-server execution model and is currently available on
four UNIX platforms:  IBM RISC System/6000 family, Silicon Graphics IRIS
Indigo and IRIS Crimson, Hewlett-Packard 700 series and Sun Sparcstation
2. 

Data Explorer is very flexible and easily adaptable to new applications
and data because it is built on a foundation of an integrated,
discipline-independent data model.  This data model describes and
provides uniform access services for any data brought into, generated
by, or exported from Data Explorer.  An important consequence of this
approach is that operations in Data Explorer are polymorphic and
interoperable.  A programming API for the data model enables users to
easily extend the system.

With Data Explorer, different visual techniques can be combined within
a single image.  For example, opaque and translucent surfaces and
translucent volumes with multiple light sources.  Multiple views of data
can be seen simultaneously.  Views can be from any direction, outside or
inside the object.  Objects can also be clipped by an arbitrary plane to
show the inside. 

Data Explorer also includes nonvisual functions for the manipulation,
transformation and analysis of the data before and after it is realized.
And of course, once images have been generated, they can be stored,
viewed, individually or as animations, and transmitted to recording
devices and across networks.

Data Explorer's graphical user interface offers significant power and
ease of use and works in a standard interface environment using
OSF/Motif and the X Window System.  Data Explorer's visual program
editor makes creating visualizations simple.  A textual scripting
language is also available for creating visualizations.  

The following summarize the various functions within Data Explorer, as
well as listing the currently supported platforms.  For further
information, including details on a 60 day free trial offer, please call
1-800-388-9820.
