3D freeware animation program utilizing the Bullet physics engine and DirectX. It was developed by Yu Higuchi for the "Vocaloid Promotion Video Project". The iconic "Miku staring at a goose" meme was animated in this software, and many
popular VOCALOID music videos have been animated in this software. Often abbreviated simply as "MMD". Users can customize their scene by using MikuMikuEffect which allows them to apply depth of field, bloom, and so much other interesting effects to make your MMD scene unique.
Originally mostly initialized for
dance videos, it is also a program for animating meme videos and "MMD dramas". You can
load any third
party models now, but an earlier version of this program only allowed users to load the standard Hatsune Miku model that came with the program, modeled by Animasa.
The formats this program uses are VPD (Vocaloid Pose Data, used for loading static pose data), VMD (Vocaloid
Motion Data, used for loading animated
motion files with keyframes), PMD (Model format used for loading models, albeit a
bit legacy), and the newer format, PMX.
