What is the .OFF File Extension?

.OFF File Extension Description:

Randi Rost created The OFF file extension in 1986 at Digital Equipment Corp.'s Workstations Systems Engineering in Massachusetts.

The OFF file extension stands for Object File Format. This file format is utilized for storing object code and information that are usually generated by an assembler or a compiler. Files with .off file extension are ASCII files, which begin with the OFF declaration. The following line is composed of the number of vertices, number of edges and faces.

The OFF file extension is generally utilized by the Princeton Shape Benchmark, a database of three-dimensional models which were accumulated from the Internet and a package of software tools for comparing or classifying shape matching algorithms. The Princeton Shape Benchmark offers aggregate semantic tags for each three-dimensional model.

Files with .off file extension are utilized to describe a model's geometry by defining the polygons of the surface of the model. This file extension can be used for a vast array of object types. OFF files are capable of handling complicated objects such as an array of vertices, a variety of attributes and polygons. The OFF file extension also addresses the undiversified case of a three-dimensional object and not a single specific case.

Files with .off file extension are extensible, meaning these files can simply be drawn out to support other primitive or expressions like bezier patches. The most significant data about an object is written in the OFF header file for the object.

There are property types or data file types that are currently being supported by the OFF file format and these include generic, indexed_poly and indexed of the line. ASCII text files are supported by the OFF file extension as a means of bringing operating system and hardware-independent object data files. The OFF file format is not designed to be constrained upon programs as an internal format but should be well-thought out as a means for keying object descriptions in an operating system and language-independent format.
