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.

X3D Extensible 3D File

An open-source, royalty-free standard developed by the Web3D Consortium. X3D uses XML encoding to represent 3D scenes and models. This versatile format excels in web-based 3D graphics, offering real-time rendering capabilities, animation support, and seamless integration with HTML5. Its extensible design makes it ideal for VR/AR applications, engineering visualizations, and interactive simulations.

Key Features of X3D/X3DB

  • Legacy:

    Direct successor to VRML with backward compatibility.

  • Web Integration:

    Designed for HTML5 (X3DOM, Three.js compatibility).

  • Scene Graph:

    Hierarchical organization of nodes (transformations, groups, etc.).

  • File Structure:

    XML-based encoding with human-readable/textual representation.

X3D/X3DB File Conversion

Autoconverter and Automesher Application offer full support for X3D file conversion, ensuring smooth interoperability between X3D and major 3D formats like STL, OBJ, SKP, 3DS, and STEP. Using our effective X3D converters you can easily transfer mesh models to and from this web-friendly 3D standard while preserving geometry, materials, and scene hierarchy.
