Definition: U3D


(Universal 3D) A 3D graphics format developed by Intel and the 3D Industry Forum (3DIF) for sharing 3D drawings on the Web and in common office applications. In order to reduce the U3D file size for quick Internet downloading and fast rendering on screen, most of the engineering data associated with the original drawing is eliminated. U3D was not designed to offer another 3D file type for editing, but to create a simple format for interactive viewing that CAD programs can export to. In late 2004, Adobe announced support for U3D in Version 7 of its Acrobat/PDF product family.
