OPC Group Updates Viewperf Benchmark;
Replacing CDRS with ProCDRS Viewset
December 1998 -- SPEC/GPC's OpenGL Performance Characterization
(OPC) project group has completed a new version of its Viewperf 3D graphics
benchmark and introduces a new viewset designed with Pro/DESIGNERTM
software from Parametric Technology Corporation (PTC). ProCDRS-01
replaces the CDRS-04 (Conceptual Design Rendering Software) viewset.
Viewperf 6.1 allows the OPC group to work with independent software
vendors (ISVs) to update and add to its current viewsets. It includes
support for features such as multiple primitive types, multiple
textures, texture objects, and explicit texture coordinates. Initial
performance results for ProCDRS-01 and updated viewsets running
under Viewperf 6.1, as well as free downloads, are available on
this site. Viewset performance results under Viewperf 6.1 should
be comparable with those reported under Viewperf 5.0 and later
Viewperf benchmark software measures the 3D rendering performance of
systems running under the OpenGL application programming interface (API).
Viewsets are the test files that run under Viewperf. Developed for the
OPC group by ISVs, viewsets represent the same mix of graphics rendering
and manipulation found in the actual applications.
Pro/DESIGNER is part of Parametric Technology Corporation's Industrial
Design Solutions. It is a comprehensive software package that contains
powerful tools to easily create, modify and evaluate complex, free-form
models. The accuracy of the surfaces created in Pro/DESIGNER enables
the geometry to be used directly by engineering -- thoroughly integrating
the design-through-manufacturing cycle.
PTC implementation engineers worked with the OPC group to develop the
new ProCDRS-01 viewset, ensuring that it represents real-world user
interaction with graphics models and operations.
"Benchmarks and test files have to change with graphics technology,"
says John Spitzer of Raycer Graphics, chair of the OPC project group.
"We updated Viewperf and its viewsets to better reflect the newest generation
of applications and to ensure that there's enough headroom to meet the
benchmarking demands of current and future graphics systems."
