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.

Test	Weight	DX functionality represented
1	40%	TMESH's immediate mode.
2	20%	LINE's immediate mode.
3	10%	TMESH's display listed.
4	8%	POINT's immediate mode.
5	5%	LINE's display listed.
6	5%	TMESH's list with facet normals.
7	5%	TMESH's with polygon stippling.
8	2.5%	TMESH's with two sided lighting.
9	2.5%	TMESH's clipped.
10	2%	POINT's direct rendering display listed.

Performance-wise, the GeForce tramples over the GVX1 once again but both cards offer respectable performance. The GeForce's more powerful T&L engine gives it the performance benefit here. Driver issues seemed to hold the GVX1 back in some of the lower tests that didn't count as much as the first two since there is no reason that the VX1 should be outperforming it in any case.

Once again, a very similar situation. The GeForce is on top with a respectable 3Dlabs following.
