What is the .OBJ File Extension?

.OBJ File Extension Description:

The file extension .obj generally applies to object files that are applied to various program types, and initially developed by Intel Corporation for software applications, designed to execute on their 80x86 microprocessors. The file extension .obj gained popularity since the MS-DOS Operating System environment, and has become the industry standard as described by the Tool Interface Standards Committee.

More recently, the file extension .obj has found extensive deployment in the field of 3D graphics (image) creation and manipulation, implemented by various imaging programs. The file extension .obj primarily acts as storage for data, relevant to the processed image that may incorporate surface data, coordinates, maps, and even textures. One of the most common applications to utilize the file extension .obj is the Advanced Visualizer, from which like many applications in its class, applies the .obj file extension in defining properties and geometries of objects.

The file extension .obj can also act as transfer container that allows the sharing of geometric information between similar programs. The contents of the file extension .obj can either be in binary or ASCII format, which associates it with the MOD format file. Free-form and polygonal objects are some of the elements supported by the obj. file extension, wherein polygonal encompasses the use of faces, lines and points in defining objects, while surfaces and curves are implemented for free-form.

The file structure of an .obj file extension can include different types like geometric and texture vertices, normals (vertex), parameter space, rational, as well as non-rational forms (used with surface types and curves), degree, basis matrix, and step size. The elements associated with the file extension .obj can be classified as surface, 2D curve, curve, face, line, and point.

The concept of rendering or display in the context of the file extension .obj, refers to the process of projecting an object within a model. The attributes applied are for polygonal and free-form geometry, which incorporates shadow casting, ray tracing, and material name. Color interpolation on the other hand, is the method where colors are blended across a polygon's surface, occupying the area between two vertices.
