title: Can somebody recommend a good U3D library?
body: <p>I need to put some 3D images into PDF files, and PDF uses Universal 3D (U3D) formats.  I don't like the U3D Sourceforge project (basically what Intel released after the ECMA standardization effort).</p>
  
  <p>Does anybody know of good U3D libraries I could use?  I'm using C++ on Microsoft Windows, FWIW.</p>
