What is obj stands for?

"obj" stands for Object file format. It is a computer file format used for storing 3D geometry data for computer graphics. OBJ files typically contain information about the vertices, edges, faces, and textures of a 3D object. OBJ files are widely used in 3D modeling applications and can be imported into various software programs for further processing or visualization. The format is supported by many 3D modeling software including Blender, Autodesk Maya, Rhino 3D, and many others. OBJ is an ASCII-based format, which means the data stored can be read by a text editor, making it human-readable.
