Pro/Engineer Viewset (proe-02)
The proe-02 viewset was created from traces
of the graphics workload generated by the Pro/ENGINEER 2001™
application from PTC.
Two models and three rendering modes are measured during the
test. PTC contributed the models to SPEC for use in measurement
of the Pro/ENGINEER application. The first of the models, the
PTC World Car, represents a large model workload composed of 3.9
to 5.9 million vertices. This model is measured in shaded, hidden-line
removal, and wireframe modes. The wireframe workloads are measured
both in normal and antialiased mode. The second model is a copier.
It is a medium-sized model made up of 485,000 to 1.6 million vertices.
Shaded and hidden-line removal modes were measured for this model.
This viewset includes state changes as made by the application
throughout the rendering of the model. For example, the PTC World
Car shaded frames include more than 100MB of state and vertex
information per frame. Examples of the included state are matrix
changes, material, light state, line stipple, etc. All state changes
are derived from a trace of the running application. The state
changes put considerably more stress on graphics subsystems than
the simple geometry dumps found in older viewsets.
Mirroring the application, draw arrays are used for the shaded
tests and immediate mode is used for the wireframe. The gradient
background used by the Pro/E application is also included to better
model the application workload.
Tests are weighted 1/3 wireframe and 2/3 shaded.
