The OFF file format is a general-purpose text file format used to represent 3D models and their associated geometry. The format, also known as Object File Format, compared to other 3D formats such as FBX, is very simple in its capabilities.
The main limitation is that it is only able to store the vertex and face information of the 3D model. Material information, textures, and face or vertex colors are not supported. Along with these limitations, the format is plain ASCII text, meaning large or complex 3D models will lead to very large OFF files being produced.
OFF files can be opened in most 3D modeling applications. Where integrated support may be lacking, there are usually third-party plugins and modules that can add support for OFF files.

The PLY format, also known as the Standard Triangle Format, is a popular 3D model file format originally created by Stanford University in the 1990s as a means to store 3D model data in a flexible and expandable format. There can be both binary and ASCII text formats in PLY files.
Both binary and text formats share a common header section that defines what geometric attributes (such as vertices, normals, faces, and colors) are present in the data. It is also possible to specify custom data to be associated with a vertex or object face.
PLY files can be opened with a wide range of 3D editing software; for example, Blender can both import and export to the PLY format with no additional software required.
