Thanks for posting this very helpful list Phillip.

The X3D CAD group is working on CAD export portability.  Perhaps you 
want to subscribe to that mailing list.  More about X3D CAD at


Knowing what 3D -> X3D exporters work with NURBS will be helpful. 
Perhaps at some point we can provide server-based solutions that scan 
for IFS/triangle meshes and surface-fit NURBS replacements.  If anyone 
knows of open-source Java that can perform that trick, then we might 
even integrate it into X3D-Edit.

the jgeom site provides a good NURBS library, but I don't think that 
includes surface fitting.

We reported yesterday regarding how Geometry2D support has gotten pretty 
good in X3D players.  Next up will be reviewing our inventory of NURBS 
support in X3D players.  Our goal is to have a workable CAD/mobile 
profile defined and deployed for X3D v3.4 by the end of the year.  Our 
slideset materials will all be getting updated and refreshed over the 
next 2 weeks in anticipation of SIGGRAPH.

All participation and contributions are welcome.  Again thanks for 
starting this discussion.
