This format is compatible with many CAD and 3D graphics applications. U3D: Full name: Universal 3D: File extension.u3d: MIME type: Developed by: 3D Industry Forum, Ecma International: Type of format: Description: Universal 3D File Format with three-dimensional model information like shapes, textures, lighting, shading and motion data. The 1stEdition of the U3D File Format was adopted by the General Assembly of December 2004. The format was later standardized by Ecma International in August 2005 as ECMA-363. The first edition is supported by many/all of the various applications mentioned below. U3D (Universal 3D) is a compressed file format and data structure for 3D computer graphics. The consortium promoted also the development of an open source library for facilitating the adoption of the format. ... Universal 3D Sample Software formerly at "Embedding interactive 3D object in a PDF using MeshLab and U3D… "Universal 3D", which is released under the The format was later standardized by Ecma International in August 2005 as ECMA-363. by Acrobat Reader (since version 7). Standard ECMA-363 Universal 3D File Format 1st edition to 4th edition (June 2007) This Standard defines the syntax and semantics of the Universal 3D file format, an extensible format for downstream 3D CAD repurposing and visualization, useful for many mainstream business applications. One such block widely deployed is the RHAdobeMesh block, which provides a more compressed alternative to the mesh blocks defined in the first edition. Universal 3D (U3D) is a compressed file format standard for 3D computer graphics data. I would like to include 3D elements in my PDF training documentation. The fourth edition provides definitions for higher order primitives (curved surfaces). The second and third editions correct some errata in the first edition, and the third edition also adds the concept of vendor specified blocks.
