Has anyone heard any news on the National Computer Graphics Associations
(NCGA) Graphics Performance Characterization (GPC) committee? Is Silicon
Graphics Inc. one of the several graphics hardware vendors supporting the
effort?
The GPC is supposedly putting together some standard benchmarking suites
to help make typical vendor performance characteristics like vectors/sec,
polys/sec, and image rotation, more well defined by including size, attributes,
orientation, etc. A GPC 'Picture-Level Benchmark' for measuring the speed at
which a 3-d picture is being displayed (shaded, rotated, transformed, etc.) is
scheduled to be released this August.
Of course nothing will completely replace the "plug in your application
and give it a spin" benchmarking, but this sounds promising.

NCGA GPC: This effort is dorminant.
Our effort is largely dorminant (Bay Area ACM/SIGGRAPH
Technical Interest Group on Performance Evaluation of Graphics
Systems). We have to start meeting again (typically at SUN or SGI).

Silicon Graphics is one of the sponsors of the GPC project. The benchmarks are currently in the final stage before the first release. The GPC committee expects to demonstrate full working versions of the benchmarks at SIGGRAPH. Anyone may bring their own data set and run it on all of the sponsors' machines at the show. To get more information about the benchmark ( including a copy of the file formats ), contact Bob Willis at NCGA: National Computer Graphics Association 2722 Merrilee Drive Suite 200 Fairfax, VA 22031 (703) 698-9600 Silicon Graphics intends to have a Graphics Library version of the benchmark in our booth at the show. You will need to ask for Mark Daly at our booth for a demonstration. Gene Miya responded to the original GPC query by refering to TIGPE. Silicon Graphics is also participating in the TIGPE group. This group is cooperating with the GPC committee ( and actually has members who attend both groups' meetings). The work done by GPC is on a "Picture Level Benchmark (PLB)" while the work being done by TIGPE is more of a features benchmarks (e.i. vectors per second or polygons per second). If you have any further questions on these, you can contact me directly via e-mail. Keith Seto keith@sgi.com

So what exactly will the benchmarks at SIGGRAPH show? Are these just how fast you can display a canned picture? -- Brent L. Bates NASA-Langley Research Center M.S. 294 Hampton, Virginia 23665-5225 (804) 864-2854 E-mail: blbates@aero4.larc.nasa.gov or blbates@aero2.larc.nasa.gov
