X3D CAD Working Group
The X3D CAD Working Group is now entering its third generation of development effort. Following many years of steady progress by Web3D members, we transitioned our efforts to the Web3D Public X3D Wiki. Further work continues.
Our current activities include:
- Consolidating, reporting and linking past achievements with CAD Geometry Component in X3D
- Continuing implementation of the X3D Compressed Binary Encoding (CBE) for reduced file size and faster loading performance
- Continuing the implementation and evaluation of Boundary Representations (B-REPS) in X3D
- Considering the use of Macro-Parametric Translation for conversion of many CAD formats into X3D
- Building a set of example models to confirm correct operation and encourage the evolution of best practices
Working group co-chairs are
- Don Brutzman, Naval Postgraduate School USA
- Hyokwang Lee, PartDB and Web3D Korea Chapter
- Marc PETIT, Electricite de France (EDF)
We have begun a X3D CAD People page to summarize our interests. New participants are welcome.
Resources
- The X3D CAD Component summary slideset describes current and planned capabilities
- Current X3D specification status is recorded at CAD Component changes for X3D v3.3, and X3D CAD Component modifications have been submitted to ISO
- Survey report TC184 Visualization Requirements for X3D CAD evaluates X3D suitability for CAD
- Corresponding ISO response ISO TC184/SC4 Comparison Report evaluating COLLADA, X3D, 3D XML, JT, and U3D
- Prior work, still continuing: Boundary Representations (B-REPS)
- Work in progress: X3D CAD Macro-Parametric Approach for Translation
- CAD Example Scenes in XD Basic Examples Archive
- STEP-NC WebGL Demo A summary of the relation between a recently developed WebGL application for CAD/CAM content and X3D.
- NURBS Patch Surface demonstration scenes and explanations for implementations by Vincent Marchetti
- NURBS Trimmed Surface Examples of NurbsTrimmedSurface node with internal trimming curves by Vincent Marchetti
- E-mail list for Web3D CAD working group members: cad@web3d.org with subscription page
- with old archives prior to March 2009 and new archives
- Members-only wiki
Events and Meetings
We hold teleconferences every other week at alternating times for Korea-USA and Korea-Europe discussion.
- Korea-USA : 17:00 PDT 2nd Wednesday (09:00 KST 2nd Thursday)
- Next meeting : May 9 Wed 17:00 PDT (May 10 Thu 09:00 KST)
- Korea-Europe : 08:00 UTC last Thursday (10:00 FST, 17:00 KST) - Please always refer to the rescheduled one!!
- Next meeting : April 20 Fri 08:00 UTC
Several Web3D presentations at SIGGRAPH 2011 covered CAD topics.
- Lee, Hyokwang (PartDB): CAD to X3D Conversion with CAD Assembly Structure
- Keil, Jens (Fraunhofer): Extending X3D for AR/MR Apps includes multiple slides (6 7 14-19 24-25 29-31 38 51) demonstrating industrial CAD applications of Augmented Reality
Meeting minutes:
Next Steps and Future Work
- X3D Binary Compression Capabilities and Plans
- Update this wiki to include all aspects of a working group charter
- Design a cool logo, both in 2D and 3D! A special prize will be awarded to whoever wins working-group approval for their design.
- CAD Working Group Strategy
