The foundation of this new 3D capability is the industry-developed Universal 3D (U3D) format for computer graphic files, which has been standardized by the European Computer Manufacturers Association (ECMA) as Standard ECMA-363 - Universal 3D File Format. U3D is natively supported by the PDF format and can be simply embedded (and compressed) in a PDF file for interactive 3D viewing in Acrobat Reader.
