U3D file format information

Full NameUniversal 3D
Type3D Model
Mime Typemodel/u3d

U3D files are a 3D model format designed specifically for use in conjunction with PDF documents. The U3D format stores 3D model data in a manner that allows the file to then be embedded within a PDF document, enabling rich 3D content within a standard PDF.

Within a U3D file are the various data elements that make up the 3D model, including vertices, faces, normals, and texture coordinates. Along with this basic geometry, the face materials are also stored, which describe how the 3D object's surface should be rendered.

Support for exporting 3D content to the U3D format can be found in some 3D modeling software; in particular, the popular modeling software Daz Studio contains a U3D exporter.

U3D Converter Capabilities

Currently, our U3D converter can only convert from U3D files, our developers are working to allow converting to U3D files in future versions of our tools. 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.
