2. Would we dare to define 3D visualization ?
entertain
3D visualization as the visual presentation on a screen or another media of graphical and textual 3 dimensional representations of a set of data representing objects, information or results of 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

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 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.

4. STEP and visualization @ SC4
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

Is there an opportunity of a JWG on visualization along ISO TC ?

6. Objectives & Next steps
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
IS is an International Standard for the computer-interpretable representation and exchange of 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 provides an integrated framework for the interoperability of the product data exchange and management along the life cycle of the product. The STEP framework is divided in Application Protocols.

11. STEP standards in the cross organizations processes
In the STEP standards, processes are defined as reference activities but they are not part of the standard. 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.

Next steps
Consolidate experience from SC4 report on visualization with latest developments and proposals in this presentation, through an ISO Joint Working Group with SC4,  JTC 1/SC 24  (X3D), TC 171/SC 2 (3D-PDF)
14306 (JT), (Collada), (Simple STEP Geometry)  are already under SC4 umbrella.

Provide an advanced resolution for Oslo to request the creation of a JWG, inviting joint SC and liaison's organisations  to report their activities.
Push the draft ISO ed3 NWI to industry (Siemens thinks of an ed3 NWI end of 2017 or > need to double check with GAAG)
Invite X3D and 3D-PDF to SC4 and define jointly with SC4 the requirements to allow X3D and 3D-PDF to consume Geometry and other data from step files and repositories
Invite ISO community + Collada Comunity to Oslo 
Invite Prostep iViP to provide a liaison statement to Oslo 
Develop STEP optimized information models and interfaces for specialized visualization formats
Develop reference test cases and data sets and promote interoperability testing
