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 File - Open Inventor 3D Scene Format
The IV file format, also known as the Open Inventor format, is a text-based 3D graphics standard originally developed by Silicon Graphics (SGI). Designed for complete 3D scene representation, IV files use hierarchical scene graphs to define geometry, lighting, materials, and textures. The format played a key role in early 3D development and is tightly integrated with the Open Inventor API - an object-oriented C++ toolkit used in scientific visualization, CAD, and simulation.
Key Features of IV Files
- Readable File Structure: Human-friendly ASCII format that organizes 3D content using nested nodes for easier editing and scripting.
- Scene Graph Hierarchy: Defines parent-child relationships between 3D objects using a directed acyclic graph (DAG) structure.
- Rich Visual Metadata: Includes lighting, shading, camera settings, and full material definitions (specular, ambient, diffuse, transparency).
- Texture Support: Handles both procedural and raster-based textures using UV mapping coordinates.
- Legacy Compatibility: Ideal for scientific and engineering applications that still rely on Open Inventor-based platforms.
Convert IV Files to FBX, glTF, OBJ, and More
Use Autoconverter to easily convert IV files to modern 3D formats like FBX, glTF, STL, OBJ, and DAE. Our IV file converter preserves full scene structure, materials, and geometry, bridging the gap between legacy and modern 3D workflows. Whether you are updating legacy data or working in cross-platform 3D environments, Autoconverter makes IV file conversion seamless and reliable.
