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.


IV Inventor File

The IV format is a 3D graphics file standard developed by Silicon Graphics (SGI) for representing complete 3D scenes. As a text-based format, it stores hierarchical scene graphs containing geometric shapes, materials, lighting, textures, and environment properties. Closely tied to the Open Inventor toolkit, this format served as a foundational C++ library for 1990s 3D graphics development.

Key Features of IV

  • File Structure:

    Uses human-readable ASCII encoding with nested node hierarchies that organize 3D scene elements.
  • Format Origin:

    Developed by Silicon Graphics in the early 1990s as the native file format for their Open Inventor 3D graphics toolkit.
  • Scene Representation:

    Implements a directed acyclic graph (DAG) structure to define parent-child relationships between 3D objects.
  • Visual Attributes::

    Stores comprehensive material definitions including ambient/diffuse/specular colors, shininess, and transparency.
  • Texture Mapping:

    Supports both procedural and image-based textures with UV coordinate mapping.
