Data Explorer Viewset (dx-08)
The IBM Visualization Data Explorer (DX) is a general-purpose
software package for scientific data visualization and analysis.
It employs a data-flow driven client-server execution model and
is currently available on Unix workstations from Silicon Graphics,
IBM, Sun and Hewlett-Packard. The OpenGL port of Data Explorer
was completed with the release of DX 2.1.
The tests visualize a set of particle traces through a vector
flow field. The width of each tube represents the magnitude of
the velocity vector at that location. Data such as this might
result from simulations of fluid flow through a constriction.
The object represented contains about 3,000 triangle meshes containing
approximately 100 vertices each. This is a medium-sized data set
for DX.
Test Weighting
All tests assume z-buffering with one light in addition to specification
of a color at every vertex. Triangle meshes are the primary primitives
for this viewset. While Data Explorer allows for many other modes
of interaction, these assumptions cover the majority of user interaction.
The first version of this viewset included indirect rendering
to handle the client/server model of X-Windows-based systems.
In this version, tests with indirect rendering have been removed
to allow the viewset to be fully ported to Windows NT and OS/2
environments.
