The OBJ file format is a widely used file format for 3D models. It was developed by Wavefront Technologies and has become a standard for representing 3D model data. OBJ files can store information about the geometry, materials, textures, and other properties of a 3D model. The format is simple and human-readable, making it easy to work with and compatible with many 3D modeling and rendering software. OBJ files can be used to store and exchange 3D models for various applications such as computer graphics, virtual reality, and 3D printing. Understanding the structure and features of the OBJ file format is essential for anyone working with 3D models and related technologies.
