Planned extensions and improvements
• Extension of the current compression module
• Adding a new Shading Model to the U3D
• Completion of the Free-Form Surface (NURBS, Bezier, B-Spline) integration
• Adding Hierarchical Subdivision Surfaces to the U3D Format
• Adding PMI Support
• Removing conflicts in the specification and precise definitions

Seems so.
I hope to hear from Intel people here, but the hope is slim.
IMHO
The only one to adopt u3d was Adobe.
All others just made converters in order to produce 3D PDF.
But that adoption was somewhat half-hearted,
since the U3D player in Acrobat/Reader is not the Intel one.
It seems Adobe is not going to develop (and, may be, actively support),
U3D now, once they have PRC format, that supports many of
what was planned for future U3D versions.
At least Acrobat 9 SDK includes API for making not U3D but PRC models.
I am teaching math to humanitarians, thus any visual helpers are more then welcome.
Making students install some 3D viewer or 3D math graphic calculator turns out to be problematic,
while Adobe Reader is everywhere.

hello,
In the "HelloWorld",i saw this:
Create Author mesh component
result = IFXCreateComponent(CID_IFXAuthorMesh, IID_IFXAuthorCLODMesh,(void**)&pAuthorClodMesh);
why not "IID_IFXAuthorMesh" ?
What's the differences between the Authormesh and the
AuthorClodmesh ? In the SamplePlayer,how to get the Authormesh?
and where are the face,line and point data stored in? how to
get access to those data?
thanks very much !
Sincerely, chen
is u3d dead?

PS. did you read History sections of

Thanks for your help Michail.
I know little about u3d,only a few items can be found through
the internet everytime.
BTW:
Did you knew any practical applications based on u3d in your
company or around you ? Any information can be provided ?
thanks again.
Applications I am interested in are in the field of educational/scientific graphics.
A good review of the ideas I am "inspired by" is in

Two other examples (interesting from _my_ point of view) are

BTW, what do _you_ intend to use u3d for?
