ProCDRS-03 Viewset

The ProCDRS-03 viewset is an update to ProCDRS-02 (which was a complete update of the CDRS-03 viewset). It is intended to model the graphics performance of Parametric Technology Corporation's CDRS industrial design software.

For more information on CDRS, see the CDRS 2000i Web Site.

The viewset consists of ten tests, each of which represents a different mode of operation within CDRS. Two of the tests use a wireframe model, and the other tests use a shaded model. Each test returns a result in frames per second, and a composite score is calculated as a weighted geometric mean of the individual test results. The tests are weighted to represent the typical proportion of time a user would spend in each mode.

The model data was converted from OpenGL command traces taken directly from the running CDRS software, and therefore preserves most of the attributes of the original model.

This viewset uses features that require SPECviewperf™ 6.1.2.

The new ProCDRS-03 viewset doubles the display list size by adding a second truck to the frame. The triangle and line counts increased accordingly.

The shaded model is a mixture of triangle strips and independent triangles, with approximately 562,000 vertices in 9,300 OpenGL primitives, giving 262,000 triangles total.

The wire frame model consists of only line strips, with around 404,000 vertices in 37,000 strips, giving 388,000 lines total.

All tests run in display list mode. The wireframe tests use anti-aliased lines, since these are the default in CDRS. The shaded tests use one infinite light and two-sided lighting. The texture is a 512 by 512 pixel 24-bit color image. See the script files for more information.
