Hi to Pisa,
just wondered whether you could support the *fbx file format.
A free offered plugin for the quicktime player from autodesk makes it possible to view the meshes interactive in this player. Think that is as intersting as the u3d format, to present the meshes in web application.
See http://usa.autodesk.com/adsk/servlet/index?id=6837478&siteID=123112
Thanks

FYI, my earlier request for FBX support, see

was closed because the FBX SDK is not Open Source ...
