MMD stands for MikuMikuDance, which is a freeware animation program that allows users to create and animate 3D films. It was originally produced for the Vocaloid character Hatsune Miku and was programmed by Yu Higuchi as part of the VOCALOID Promotion Video Project (VPVP). MMD is exclusively a posing and animation software, so modelers use 3D modeling software such as Blender or Metasequoia to create the model and UV map, while the majority of conversion to the MMD platform is done with a program made exclusively for MMD model conversion, PMD Editor or its successor PMX editor. MMD is a modern DirectX video game without the game, and it is a powerful game-system framework that awaits creative genius to create 3D animations. MMD is also the abbreviation for Myotonic Muscular Dystrophy, which is a multisystem disorder that affects the brain, skeletal and smooth muscles, eyes, heart, gastrointestinal tract, lungs, and other organs.
