What is obj meaning?

OBJ stands for Object file format, which is a standard file format used to represent and exchange 3D geometry between different computer graphics software programs. It was first introduced by Wavefront Technologies in 1988 and has since become one of the most widely used file formats for 3D models. The OBJ file format can store mesh data, vertices, textures, materials, and animation data. It can be easily imported and exported by most 3D modeling and animation software programs, making it an important tool for creating and sharing 3D models.
