Data Explorer (DX-05) Viewset

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, Hewlett-Packard and Digital Equipment. The OpenGL port of Data Explorer was completed with the recent 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 1,000 triangle meshes containing approximately 100 verticies each. This is a medium-sized data set for DX.
The Pentium III is completely dominating here, the Athlon needs a faster L2 cache in order to help keep up. The added memory bandwidth of the i820 chipset (courtesy of RDRAM) gives Intel an even more noticeable lead at 800MHz. While they weren't included, moving to an i840 platform with double the memory bandwidth would most likely yield a very impressive performance boost here as well.
