File format information for U3D and OBJ

Full NameUniversal 3D
Type3D Model
Mime Typemodel/u3d

The U3D file is a 3D file format (Universal 3D) developed by a consortium of well known companies in 2005 with the idea of creating a standardized file format for storing 3D data including mesh vertices, textures, bones and effects.

U3D files are binary in nature containing a block based structure which following later revisions could be extended with custom blocks.

U3D Converter Capabilities

Our U3D 3D Model/Mesh tool does not support any color material data contained within U3D files so the converted file will not contain any color information.

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.

As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.

Information for converting from U3D to OBJ

Your U3D file will be converted to a OBJ file using our unified 3D model and mesh conversion tool. Our U3D 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your U3D file, your final 3D model will contain geometry data only.
