    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?

      i saw the following:
      Universal 3D Road-map - 2007/2008
      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.

      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

      http://astronomy.swin.edu.au/s2plot/3dpdf/davidgbarnes-submitted-version.pdf

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

      http://www.oucom.ohiou.edu/dbms-witmer/Majungasaurus-skull03.htm

      and

      http://asymptote.sourceforge.net/gallery/3D%20graphs/.index1.html

      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.

      As to vendor-supplied histories of successful sales - one more place to visit is

      http://www.pdf3d.org/

      BTW, what do _you_ intend to use u3d for?
