OFF Object File Format

A straightforward, human-readable file format designed for representing 3D polygonal models. As a lightweight alternative to complex CAD formats, OFF focuses on storing essential geometric data - vertices, edges, and faces - without proprietary constraints.

Key Features of OFF

  • ASCII Text Files:

    : OFF files are text-based and use a simple syntax to store geometric data of 3D objects. The files can be easily edited and viewed with any text editor or viewer.

  • Polygonal Shapes:

    The OFF format allows to store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.

  • Limitations:

    OFF files support only geometric data - materials, textures, and group names from source files are discarded during conversion.

OFF File Conversion

Our software offers two specialized approaches for OFF file conversion. Autoconverter handles conversion of OFF files to common mesh formats including STL, SKP, OBJ, and PLY, maintaining the original polygonal structure. Autoshaper provides advanced conversion of OFF polygonal data into smooth NURBS surfaces, exporting to BREP, STEP, and IGES formats for CAD workflows.

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

Autoconverter simplifies the process of converting your 3D models into the IV format, ensuring seamless compatibility with both legacy and modern 3D tools. Our IV files converter preserves your geometry, materials, and scene hierarchy in a human-readable structure that remains editable across workflows. Still using legacy Open Inventor tools? Convert modern FBX/glTF models to pristine IV format with Autoconverter today!
