Description: 3D PDF with Universal 3D (u3d) file format:

  • Portable Document Format (PDF) is a file format for document exchange. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a fixed-layout 2D document (and, with Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics which compose the documents. [1]
  • Universal 3D (U3D) is a compressed file format standard for 3D computer graphics data. [2]

History: Adobe and Universal 3D: The Universal 3D format was defined by a special consortium called 3D Industry Forum that brought together a diverse group of companies and organizations, including Intel, Boeing, HP, Adobe Systems, Bentley Systems, Right Hemisphere and others whose main focus had been the promotional development of 3D graphics for use in various industries, specifically at this time manufacturing as well as construction and industrial plant design. The format was later standardized by Ecma International in August 2005 as ECMA-363. The goal is a universal standard for three-dimensional data of all kinds, to facilitate data exchange. The consortium promoted also the development of an open source library for facilitating the adoption of the format. The format is natively supported by the PDF format and 3D objects in U3D format can be inserted into PDF documents and interactively visualized by Acrobat Reader (since version 7). [3]

Example(s): 3D PDF Examples - Information and example models of the engineering format.
