EnSight Viewset (ensight-03)

The ensight-03 viewset provides the ability to compare display list and immediate mode paths, and additional quality checks for display list results. It represents engineering and scientific visualization workloads created from traces of CEI's EnSight application.

CEI contributed the models and suggested workloads. Various modes of the EnSight application are tested using both display-list and immediate-mode paths through the OpenGL API. The model data is replicated by SPECviewperf 9 to generate 3.2 million vertices per frame.

State changes as made by the application are included throughout the rendering of the model, including matrix, material, light and line-stipple changes. 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, both immediate-mode and display-list modes are measured. See notes on specific tests for more information.
