IGS, which stands for Initial Graphics Exchange Specification, is a widely used file format in the realm of computer-aided design (CAD) and computer-aided manufacturing (CAM). It was developed in the 1980s to enable the seamless exchange of 2D and 3D geometry data between different CAD software systems. The IGS file format serves as a neutral intermediary, allowing various CAD applications to communicate and share complex geometric models without compatibility issues.

IGS files are essentially text-based representations of geometric data, describing not only the shape and structure of objects but also attributes such as colors and layers. These files can encompass a wide range of information, including points, lines, curves, surfaces, and solids, making them versatile for sharing complex engineering and design information. One of IGS's key strengths is its ability to preserve geometry and topology regardless of the software used, ensuring that intricate details of a design are accurately conveyed.

Over time, IGS has been largely succeeded by more modern and capable file formats like STEP (Standard for the Exchange of Product Data) and native formats used by specific CAD software. However, IGES still retains relevance in certain industries and for legacy data conversion due to its wide adoption and compatibility. Despite its limitations in handling advanced features compared to newer formats, IGS remains an important piece of CAD history, playing a vital role in the evolution of data interoperability.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.
