An OFF file, short for Object File Format, is a plain-text file used to represent the geometry of a three-dimensional object. It serves as a simple and widely-used format to store the spatial information of a 3D model. The OFF file format is not restricted to any specific software or application, making it highly versatile for exchanging geometric data among various 3D modeling and visualization tools.

Typically, an OFF file begins with a header line containing the keyword "OFF" and the number of vertices, faces, and edges in the model. The subsequent lines list the coordinates of each vertex, specifying their 3D positions in space. After that, the faces of the object are defined, where each face references a set of vertex indices that form a polygonal face. The simplicity of the OFF format makes it easy to parse and manipulate, which has contributed to its popularity in computational geometry and computer graphics research.

Despite its ease of use, the OFF file format does have some limitations. Notably, it does not support material properties, color information, or texture mapping, focusing solely on geometric representation. Additionally, it does not include any information about the topology or connectivity of the object. Nevertheless, due to its straightforward structure and widespread acceptance, the OFF file format remains a fundamental and valuable tool for sharing 3D model data across different applications and platforms.

OFF Converter Capabilities

Our OFF converter can both convert from and to OFF files and our developers are working to improve our OFF conversion tools in future versions. When converting 3D Model/Mesh files using our OFF converter we will attempt to convert color materials into a suitable format for use in the converted file.

Frequently Asked Questions

How accurate is the 3D file conversion?

Our OFF conversion tool can convert most 3D geometry including mesh vertices and faces with no loss of detail. Any color materials contained within the 3D model file will be converted where possible.

Are textures supported in the OFF conversion?

No, due to the different methods of assigning textures to a 3D model textures are not currently supported. If your OFF model contains textures or references to external texture files, these will be ignored.

Is it free to use the OFF conversion tools?

Yes! Our OFF conversion tools are 100% free to use.

Are there any OFF conversion usage limits?

No, you can convert as many files as you wish. We do not impose any conversion limits on our OFF conversion tools.

How long does it take to convert my OFF?

We aim to process all OFF conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files and significantly longer for some larger file formats, so please be patient.

What does the OFF conversion process involve?

Once your OFF file has been uploaded and we know the file format you wish to convert it to our bespoke conversion software will convert your OFF and make it available for you to download with a unique download Url.

Is it safe to convert my OFF on FabConvert.com?

Yes, of course it is! Your OFF, once converted is deleted 1 hour after upload and the download link will expire after this time.

Can I convert my OFF on Linux, Android, iOS or Mac OS?

Yes! Our OFF conversion tools will run on any system with a modern web browser.

Is there any support for me when using the OFF tool?

If you are having difficulty converting your OFF you can contact us and we will try to help where possible.
