The U3D file is a 3D file format (Universal 3D) developed by a consortium of well known companies in 2005 with the idea of creating a standardized file format for storing 3D data including mesh vertices, textures, bones and effects.

U3D files are binary in nature containing a block based structure which following later revisions could be extended with custom blocks.
