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:

We have begun a X3D CAD People page to summarize our interests. New participants are welcome.
