OFF 3D Model (.OFF)

OFF (Object File Format) is a simple plain-text 3D model format that stores polygon meshes as lists of vertices and face definitions. It was developed at Princeton University and uses a minimal header followed by vertex coordinates and face indices. OFF is commonly used in computational geometry research and academic settings due to its simplicity.

Advantages of OFF 3D Model

What the OFF format does well, and why you might choose it.

  • Extremely simple format that is trivial to parse and generate
  • Human-readable plain-text representation of polygon meshes
  • Standard format for many computational geometry research datasets

Limitations of OFF 3D Model

What the OFFformat doesn't do well, and when to choose another format.

  • No support for normals, textures, materials, or colors in the basic format
  • Not widely supported by commercial 3D software or game engines
  • Plain-text format results in large files for complex models

What OFF files are used for

  • Computational geometry research and algorithm benchmarking
  • Academic 3D model datasets and mesh processing
  • Simple polygon mesh interchange in educational contexts

Frequently asked questions about OFF

What is a .OFF file?

OFF (Object File Format) is a simple plain-text 3D model format that stores polygon meshes as lists of vertices and face definitions. It was developed at Princeton University and uses a minimal header followed by vertex coordinates and face indices. OFF is commonly used in computational geometry research and academic settings due to its simplicity.

What is the MIME type of OFF?

The official MIME type for OFF files is application/x-off. This is the value web servers and applications use to identify the format when transferring files.

What category does OFF belong to?

OFF is a 3D Model Converter format. Files in this category share common conversion paths and use cases.

How do I open a .OFF file?

OFF files are typically opened by software that natively supports the OFF 3D Modelformat. If you don't have a compatible application, the most reliable approach is to convert the file to a more universal format using the converters listed above. Most OFF 3D Model files convert to widely-supported alternatives in seconds.
