MD2

Model Data version 2 (MD2) is a 3D model file format used in Quake 2 games to load and render 3D models in games. It was developed by id Software and is part of the Quake 2 engine. The MD2 file contains information such as the geometry of a 3D object, texture mapping coordinates, and all the frame data that needs to be animated. This format is designed to be very compact so that large amounts of animation data can be stored and loaded and rendered quickly at runtime. Although MD2 is outdated, it has important implications for the history of games and the development of Computer Graphics. In addition to Quake 2, several other games have used this format.
