The 3DS format is a file format used by Autodesk's 3D Studio software for representing 3D models and scenes. It was widely used in the 1990s and early 2000s and is known for its ability to store geometric and animation data in a compact and efficient manner.

The 3DS format has played a significant role in the history of 3D graphics and modeling, providing a compact and efficient means of storing 3D models and animations. However, it has largely been superseded by more modern formats in current applications.
