U3D Universal 3D File

An open standard for 3D data exchange, originally developed by the 3D Industry Forum to enable universal 3D visualization across platforms. As a compressed, binary file format, U3D efficiently stores three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates.

Key Features of U3D

  • Open Standard:

    Royalty-free format maintained by ECMA International (Standard ECMA-363).

  • PDF Integration:

    U3D enables the generation of PDF documents that contain interactive 3D data (ISO 32000). This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document.

  • Compact Size:

    Optimized compression for web and document embedding.

  • Cross-Platform:

    Viewable across major operating systems without proprietary software.

U3D File Conversion

Our Autoconverter and Automesher Application utilize Intel's powerful open-source IFX conversion library to deliver robust U3D file conversion capabilities. This technology enables seamless two-way conversion between the U3D format and various industry-standard 3D formats including STL, OBJ, SKP, DAE, STEP, IGES, DWG, 3DS, FBX and X3D. The solution provides reliable transformation of 3D data while maintaining optimal file structure and visual fidelity throughout the conversion process.

FBX Filmbox File

A proprietary, industry-standard file format for 3D assets and animations, originally developed by Kaydara for motion capture and later acquired by Autodesk. As a universal 3D interchange format, FBX enables seamless data exchange between 3D modeling, animation, and rendering applications, while preserving complex hierarchies, textures, and animation data.

FBX Key Features

  • Embedded Texture Images: FBX files allow all texture images to be stored directly within the 3D model file, rather than as separate external files. This ensures that the textures travel with the model, making it easier to share, distribute, and maintain visual consistency across different software and platforms.
  • Reusable Geometry Components: The FBX format allows for the storage of reusable geometry components, enhancing efficiency and consistency across models.
  • Assembly Structures: FBX supports the storage of assembly structures with hierarchical relationships between objects, enabling complex and detailed 3D modeling.
  • Model Animation Data: FBX can even store model animation data, although this feature is not currently supported by all software.

FBX File Converters

Autoconverter and Autoshaper software streamline FBX workflows by enabling high-fidelity conversions between FBX and 30+ CAD/3D formats (SKP, STEP, OBJ, etc.). These tools preserve critical data - including geometry, textures, animations, and hierarchies - while offering precision control for both engineering (NURBS) and entertainment (mesh optimization) applications.
