2. Would we dare to define 3D visualization ? entertain objects learn information compare view understand decide 3Dvisualization as the visual presentation on a screen or another media of graphical and textual 3 dimensional representations of a set of data representing objects, informationor resultsof a 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 medium STEP and visualization @ SC4

3. Visualization in the STEP Framework Requirements 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 optimizedvisualization model with links to the rest of the data model. The model based STEP framework allow us to ensure consistency of the integrated informationmodel and the corresponding implementationforms. metadata activities & process planning documents simulations product structures configuration management materials alternate representations geometry primitives PMI AP242 3D geometry tesselation B-Reps CSG 2D parametric optimized representation for visualization STEP and visualization @ SC4

4. 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 3D 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 to STEP AP242 geometry conformance classes using the STEP New Architecture STEP and visualization @ SC4

6. Objectives & Next steps Objective • Publish a reference architecture for product data visualization Next steps • There are a number of proposed New Work Items and tasks related to 3D visualization and other forms of consumption of product data. These New Work Items have been raised within SC 4 and also other subcommittees. It is therefore proposed to create a new WG which may be joint with JTC 1/SC 24 and TC 171/SC 2 to undertake these work items. • In Oslo in May 2017, the ISO/TC 184/SC 4 requests its Secretariat to create the WG 16 with the following title and scope • Title: Formats for 3D Visualization and consumption of product data • Scope: • Develop and maintain standards for 3D visualization of product models, including geometry, product structure and other classes of information. • Develop and maintain standards for consumption of data derived from product models. • Develop and maintain standards for interfaces from SC 4 product definition standards. • Establish liaison with other standards activities working on information models for 3D visualization. • SC 4 requests its Secretariat to assign any NP within scope to WG 16.

8. STEP had Product Data Exchange in its genes IS0 10303 is an International Standard for the computer-interpretable representation and exchangeof product data. The objective is to provide a mechanism that is capable of describing product data throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving. STEP and visualization @ SC4

Collaboration processes are defined in order to allow organization to collaborate while still keeping their own internal optimized processes. The collaboration processes take advantage of the STEP standard. Until now, the management and decision processes were not the target of STEP. STEP and visualization @ SC4

12. Challenges for tomorrow • Multiple implementation forms (XML, J-SON, ? zigmo++ ?) • Broader community using the STEP information model • Linked data architectures (STEP / OSLC) • Hybrid solutions (STEP / X3D / JT / PDF3D) • Ensuring security, quality , shape equivalence, persitent identification STEP and visualization @ SC4
