The 2012 JT Application Benchmark is a project of the ProSTEP iViP Association and the German Association of the Automotive Industry (VDA). Aim of the benchmark is to give a neutral overview of currently available JT application’s capabilities and improve interoperability between them. For the first time, a ProSTEP iViP/VDA JT benchmark did not focus on translators only but also on viewing applications.

The source formats for the translation tests are CATIA V5 R19, NX 8 and Wildfire 5. The test models are converted to JT with settings provided by the translator vendors. Focus of the benchmark is on the quality of the tessellation and the translation of PMI.

Regarding tessellation, it is checked whether the naming and number of LODs match the settings. The angular values are checked and the chordal deviations measured. The simplification of lower LODs and the translation of model colors are checked also.

Regarding PMI, it is analyzed whether different types of PMI annotations can be translated to JT. The layout and organization of PMI is benchmarked. Color, style, size, symbols, position and orientation of the annotations shall be kept. Organization of PMI regards the links between annotations and geometry, between different annotations and the allocation of annotations to Model Views are also relevant test criteria.

Basic viewing and analysis functionalities are benchmarked in the viewer tests. The performance of the involved viewers is also measured.
