U3D Universal 3D Model Exchange - U3D File Format

The Universal 3D (U3D) format is an open, royalty-free 3D file standard designed for efficient sharing of 3D models across different platforms and applications. Originally developed by the 3D Industry Forum and now standardized by ECMA International (ECMA-363), U3D files offer compressed storage of 3D triangular meshes, along with attributes like color, transparency, and texture mapping. U3D is widely known for enabling interactive 3D graphics directly within PDF documents.

Main Features of U3D Files

  • Open and Royalty-Free: Maintained as an international standard, ensuring no licensing fees for developers and users.
  • 3D PDF Support: Integrates seamlessly with PDF files (ISO 32000 standard), allowing users to embed, view, and interact with 3D models inside Adobe Acrobat Reader and other compatible viewers.
  • Efficient Compression: Stores 3D geometry and properties in a compact, binary format optimized for fast transmission and document embedding.
  • Cross-Platform Compatibility: Enables 3D model viewing across Windows, macOS, and Linux without requiring proprietary software.

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.
