An OBJ file, short for Object file, is a 3D model file format used by various 3D modeling software to represent an object or geometry. It is a universal format that can be exported and imported across different 3D rendering software making it a widely accepted industry-standard format.

The OBJ file format was introduced in the 1980s by Wavefront Technologies, and since then it has been constantly used by various 3D modeling software in different applications. The OBJ file format contains information about the 3D model’s geometry, texture data, and material information. It is a non-parametric file format, which means that it is not associated with any specific modeling software and can be used by a wide range of modeling software.

Using an OBJ file is fairly straightforward. You can open the file using any 3D modeling software such as Autodesk Maya, Blender, 3DS Max, and many others. Once the file is opened, you can perform various 3D operations such as scaling, translation, and rotation on the object, add materials and textures, and even create animations.

One of the significant advantages of using OBJ files is that it allows users to share their 3D models easily without worrying about the compatibility of the software used. Additionally, it provides a smooth workflow for creating 3D models in different software.

Moreover, OBJ files are highly customizable. You can edit the object’s geometry, material, and texture, and save it as an OBJ file. These editing options make it easy for users to create custom models, implement specific details, or make modifications to the original model.
