The OBJ file format is a widely used file format in 3D modeling and graphics. It was originally developed by Wavefront Technologies for its Advanced Visualizer software, but it has since become a standard file format for exchanging 3D model data between different software applications. The OBJ file format stores 3D model data, including geometric and texture information, in a human-readable ASCII format, making it easy to parse and manipulate. OBJ files can contain information about vertices, texture coordinates, normals, faces, and material properties, making it a versatile and feature-rich file format for 3D modeling. One of the key features of the OBJ file format is its support for complex polygonal and free-form geometry, making it suitable for a wide range of 3D modeling tasks. Overall, the OBJ file format plays a crucial role in the field of 3D modeling and graphics, allowing for the seamless exchange of 3D model data between different software applications and facilitating the creation of stunning visualizations and virtual environments.
