OFF

OFF is a simple text format used to describe the basic geometric information of a 3D model, similar to the NFF format but more flexible and versatile.

The OFF format is more flexible than the NFF format, supporting a wider variety of surface and vertex data representations, and is suitable for a wider range of 3D model description needs.

It is typically used for simple to moderately complex 3D model storage and transmission, but may not be efficient for large-scale or high-performance loading and rendering models.
