Convert U3D to VRML: All You Need to Know

U3D to VRML: Resources

Listed below are additional resources pertaining to the interoperability and exchange of U3D and VRML files. These will be valuable in guiding you through the U3D to VRML files conversion.

U3D File U3D

The U3D (Universal 3D) file format is an open-source compressed format, initiated by the 3D Industry Forum. It’s designed to store three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates. This format plays a significant role in the general 3D graphics industry, particularly in conjunction with 3D PDF technology. It enables the generation of PDF documents containing interactive 3D data from U3D files. Both of our U3D file converters, Autoconverter and Automesher Application, are capable of reading and writing to and from the U3D file format. This is made possible thanks to the publicly available open-source IFX conversion library provided by Intel. To streamline the process of generating 3D PDF documents, our converters create a standard TEX script that can be easily utilized with free LaTeX software.


The VRML (Virtual Reality Modeling Language) is an ASCII file format used to store 3D objects along with additional attributes such as light sources, materials, textures, and world transformations. These elements are crucial for rendering the entire 3D scene in a web browser. It’s important to note that the modern and more advanced replacement for VRML is the X3D file format. With our Autoconverter and Automesher Application products, you can import and export VRML files, and convert them into various other file formats. However, please be aware that material textures are only processed for IndexedFaceSet shape geometries saved in the VRML file.
