U3D to X3D
Please find below the list of our other useful resources related to U3D and X3D interoperability and exchange that could help you with the U3D to X3D conversion.
U3D File
U3D (Universal 3D) is an open source compressed file format initiated by the 3D Industry Forum to store three dimensional triangular meshes with the additional properties e.g. color, transparency or texture coordinates for the general 3D graphics industry. The U3D file format is mostly used in combination with the 3D PDF technology which allows you to generate PDF documents containing interactive 3D data from the U3D files. Autoconverter and Automesher Application, our U3D file converters can read and write to and from U3D file format thanks to the publicly available open source IFX converter library provided by the Intel company. To simplify generation of 3D PDF documents our converters create a common TEX script which can be easily used to generate a PDF document with the standard and free LaTeX software.
X3D File
X3D (Extensible 3D) is an open source and royalty free XML based file format developed and maintained by the Web3D Consortium to store two or three dimensional models together with the other visualization data e.g. light source, viewport info, camera properties, special effects and more. The X3D file format becomes an advanced extension and actually the replacement for the original VRML (Virtual Reality Modeling Language) file format used mostly by the WEB applications. The Autoconverter and Automesher Application are our X3D file converters which allow you to import and export mesh entities from the X3D file. To optimize file size the binary X3DB file can be used instead of a default text based X3D file. The shapes in X3D files are always defined in meters therefore our X3D converters will make the necessary units conversion if required.
