Comments

U3D file format, short for "Universal 3D", is a universal vector standard for storing three-dimensional data of all kinds to facilitate data exchange. The specification for this format is the document ECMA-363: Universal 3D File Format. The latest edition of this specification is available at the ECMA web site:

www.ecma-international.org/

The U3D format is natively supported by the PDF. 3D objects in U3D format can be inserted into PDF document files and interactively visualized by PDF viewers.
