OFF OFF File Format - 3D Object File for Polygon Meshes

The OFF (Object File Format) is a simple, ASCII-based 3D file format used for representing polygonal geometry in a lightweight, non-proprietary structure. Designed for academic and development use, the OFF format efficiently stores 3D model data using only vertices, faces, and optional edge information - ideal for geometry-focused workflows without material or texture metadata.

OFF File Features

  • Editable ASCII Structure: OFF files are plain text, easily viewable and editable in any standard text editor, making them perfect for manual modeling or debugging.
  • Supports Polygonal Geometry: Store 3D shapes using triangle meshes, quadrilaterals, or general polygons. Each face is defined by a list of vertex indices, allowing flexible model design.
  • Lightweight and Minimal: Unlike complex CAD formats, OFF excludes materials, textures, and metadata, focusing purely on geometric structure for fast, efficient modeling.

Convert OFF Files to Other 3D Formats

Our 3D conversion tools make working with OFF files fast and flexible. Autoconverter enables direct conversion of OFF mesh models to popular formats such as STL, OBJ, SKP (SketchUp), and PLY - preserving polygonal integrity throughout. For advanced workflows, Autoshaper can convert OFF files into NURBS-based formats like STEP, IGES, and BREP, ideal for CAD software and precision manufacturing.

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.

IV File Conversion
