X3D CAD Working Group
The X3D CAD Working Group is now entering its third generation of development effort.
Our current activities include:
- Consolidating 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)
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
- Survey report TC184 Visualization Requirements for X3D CAD evaluates X3D suitability for CAD
- Corresponding ISO response ISO TC184/SC4 Comparison Report (also .doc version) 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
- E-mail list for Web3D CAD working group members: cad@web3d.org
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 : Oct 12 Wed 17:00 PDT (Thu 09:00 KST)
- Korea-Europe : 10:00 FST 4th Monday (17:00 KST 4th Monday)
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
Next Steps and Future Work
- Update this wiki to include all aspects of a working group charter
- Move the wiki to Web3D Public wiki - last call for any objections!
- Design a cool logo, both in 2D and 3D! A special prize will be awarded to whoever wins working-group approval for their design.
