Would we dare to define 3 D visualization ? objects 3 D visualization as the visual presentation on a entertain screen or another media of graphical and textual 3 dimensional representations of a set of data representing objects, information or results of a learn information computational process in order to: • facilitate capture of the understanding of the object, for visual information sharing with users • and sometimes to promote decision process by a human looking at the data visualized in a compare understand decide medium April. 24 th 2018 STEP Geometry Services Kick.

Visualization in the STEP Framework STEP provides a data model which integrates the whole data landscape for the product development, manufacturing operations and maintenance. The concept of multiple representations of the product, including multiple geometrical representations allows us to define an optimized visualization model with links to the rest of the data model. The model based STEP framework allow us to ensure consistency of the integrated information model and the corresponding implementation forms. April. 24 th 2018 STEP Geometry Services Kick.

Analysis • Promoting the re-use of the rich integrated STEP data model in the enterprise processes has great value • There is a confirmed opportunity for industry to have a structured approach on 3 D product visualisation and to enable integration of product data in visualization application across the life cycle of the product in all the activities of the enterprise. • Use cases exist related with the visualization of product data other that geometry (meta data, production data, financial data. . . ) • Need for STEP interfaces for geometry and other STEP data access (OSLC ? MOSSEC approach? ) • There is also a need for a simple STEP geometry schema and associated API , with and without PMI (integration with STEP New Architecture ? ) • Requirements for a STEP AP 242 geometry conformance classes using the STEP New Architecture April. 24 th 2018 STEP Geometry Services Kick.

3 D PDF & STEP Next version of ISO 32000 (-3? ) PDF will include a container for STEP geometry The strong liaisons between TC 184/SC 4 and TC 171/SC 2 is making this activity much easier. Ad Hoc group has delivered a report on how to integrate STEP into PDF. TC 171/SC 2 will contribute to the SC 4/WG 16 work. April. 24 th 2018 STEP Geometry Services Kick. Off
