Industry needs in visualization of 3D Data


Keywords & Usage :

Analysis

Sharing Information

Communication

New Technologies

SimulationInside the company – improve the dialogue between services

More explicit & easy to understand information

Improve quality of the technical documentation

Give a quicker access to realistic visualization of the product for marketing : reduce time to market

Reduce design costs by using more frequently “cheaper” simulations

New capabilities in process simulation & mechanism simulation

Use new technologies to improve recognition as a dynamic company

Most of the user do not want to manage multiple representation of the same model (multiple file or format) Complexity of data managementRisk of inconsistency between the different representation (are all of them up

to date ?)

Most of the user would like to give access only to the strictly necessary information – not more, not lessNeeds of light package for manipulation and exchange IP protection

Usage ? (VR, DMU analysis, technical doc …)Security Level ?Level of education of the target user ?Level of performance of the target IT environment ?Time to have access to the complete information ?

3D Visualization Data Main ConstraintsThe dilemma:

Usual questions:


7


Why Using Standards ?


Easy to use, easy to share, reliableDurability : the format will not completely change next year Security : the definition is public – data is independent of a third party technology1 Format for many tools

If not already available : can take a long time to get what’s you need –standardization is a long process

Difference of implementation - same format should give same results but it’s not always the case

Adoption by software vendors

Need to pay attention of the standard’s scopeThere are multiple standards that can be used for a

specific needsStandard is a tool not a solution : needs to have a

plan and to define a suitable process


8


Why Using Standards ?


All kind of 3D Data can be use for visualization – BREP, Tessellation, …Many Standard Formats Available : STEP, PDF, JT, X3D, VRML…

IN THIS PRESENTATION WE WILL CONSIDER LIGHTWEIGHT VISUALIZATION ONLY


9


Use Case 1 : Context


Short Description Easy access to 3D technical data including PMI & annotation to maintenance service of the end user

Domain Aerospace

Status In production

Usage Technical documentation for maintenance services

Security Level IP protection requested – Data needs to be simplified and precise definition has to be removed.

Target Users All kind of users

Target IT Environment The document should be displayed on very low performance machine. Installation of dedicated software forbidden.

Time To Access Information Less than 1 hour after customer request


10


Use Case 1 : Solutions


• Convert BREP to Tessellated data

• Remove unnecessary details

• Reduce number of triangles

STEP AP 242 Files

(LTAR)

Simplified 3D-PDF

Files


11




Output target format – 3D-PDF : Acrobat reader is available on many machine format is light Nearly anybody knows PDF

Simplification of the original data is necessary : Make the data lighter for low performance machine Remove most important information (IP protection)

On the fly generation of output data : Avoid to maintain a data base of results Output always up to date


12




Short Description Multi-usage of simplified visualization models in a PLM environment.

Domain Construction Trucks and Machine

Status In production

Usages • Quick visualization of a sub-component – DMU, collision ….• Illustration in the technical Documentation• Realistic display for marketing

Security Level Medium – main purpose is to obtain lighter models

Target Users Multiple internal services : documentation engineers, marketing.

Target IT Environment Designer or PAO machines

Time To Access Information Immediate


13




• Simplify Exact Data

• Merge all parts in sub-assembly

Native Data

Simplified JT Files

PLM


14





15




Make it Visual BoM & design data are managed in one integrated solution

Design artifacts are change controlled & integrated to the BoM, forming a Bill of Information

Visual Reporting facilitates improved decision making

Collaboration across extended enterprise is supported with appropriate information access

Design geometry is easily shared across the extended enterprise

Make Value Flow Downstream flow of product & process data enable success of Manufacturing and Product

Support

Sales & Marketing strategy linked to product Bill of Information

On the fly re-generation : As data are store in the PLM, we can easily determine if simplified data is up to date and

regenerate it if need.


16




Short Description Management and Control of Archive Data including Composite and PMI & Annotations

Domain Aerospace

Status In progress

Usage Analysis : Reviewing Archive Data

Security Level High

Target Users Experienced Engineer

Target IT Environment Mechanical Design Workstation

Time To Access Information Immediate


17




Native Data

Full STEP 242 ready to archive

Archive Repository

Convert into STEP AP 242 with all information (composite, PMI & GVP)

Validation

Visualization STEP 242 with

GVP

For review usage, convert to visualization only STEP file with Annotations & GVP

Archived STEP 242 with GVP

Review with STEP Viewer


18




Output target format – STEP AP 242 : Perfect for LTAR (GVP)

As light as other lightweight formats if compressed

Examples for these GVP are: Assembly, e.g. number of children and solid centroids

PMI, e.g. polyline curve length comparison

Tessellation, e.g. centroid and surface area

Composites, e.g. number of sequences and cut pieces


19


CONCLUSIONS


ON THE LIGHTWEIGHT VISUALIZATION STANDARDS : From our experience, one file/format for all needs is a mythA good practice is more a question of process than format or tools Standards are good solutions for long term processes Standards formats are structuring

ON THE VISUALIZATION PROCESSES : Simplification is the keyNeed to protect IP is strong Thanks to the increase of performance, we want now to display

everything, BUT : this is still too much for most of the machines.
