Live2D is an animation technique used to animate static images—usually anime-style characters—that involves separating an image into parts and animating each part accordingly, without the need of frame-by-frame animation or a 3D model.[1][2][3][4][5][6] This enables characters to move using 2.5D movement while maintaining the original illustration.
There is a common misconception that Live2D refers to the software used to create Live2D animation.[7][8] Due to the popularity of Live2D Cubism, people often equate Live2D (the animation technique) with Live2D Cubism (the software). However, Live2D is an animation technique, not the software used to create Live2D animation. There are other software options used to create Live2D animation, such as Inochi2D or E-mote (which is used in Tokyo School Life).[9]
Live2D models consist of layered parts saved as a Photoshop file (.psd format). Layers are separately moved to show the whole animation and expression of the character, such as tilting the head. Parts can be as simple as face, hair, and body, or they can be detailed to eyebrows, eyelashes, and even effects like glinting metal.
The number of layers depends on how you wish the Live2D character to move and how three-dimensional you wish the result to appear, with a simplified model having 50 layers and large complex projects reaching 750 layers. There is no limit to how detailed you can be, with some even modelling the sides of the teeth for full effect.[10] Unlike a 3D model there isn't a traditional skeleton, but instead the flat layers are warped and rotated.
Live2D can be used with real-time motion capture to track movements such as head movements, eye movements, and perform lip syncing for real-time applications such as vtubing. The downside of the technology is that there is little capability for 360° rotation of complex objects and body tracking.
Live2D has been used in a wide variety of video games, visual novels, virtual YouTuber channels, and other media. Well-known examples of Live2D media and software include FaceRig,[11][12] VTube Studio, VTuber Legend,[13] Nekopara,[14] Azur Lane,[15] and virtual YouTubers (as popularized by Hololive, Nijisanji,[16] and VShojo).
History
[edit]Background
[edit]Live2D was first introduced in 2008 to resolve the need for interactive media.[17] Since then, the technology has also changed how games enhance user experience through lively characters and expressions.[18]
In 2009, Cybernoids Co. Ltd. (now Live2D Ltd.) released their very first Live2D application, Live2D Vector.[19] The application transforms vector graphics to make flat character images achieve three-dimensional head turning and moving effects. Although such characters can only perform limited activities, they perform much better than static pictures or slideshows. Users can also customize their moving character by adjusting parameters through software or collecting materials such as images of different angles of a character. Of course, vector graphics still have many limitations. Although the occupied capacity resources are reduced, the rendering of complex images consumes a lot of CPU and RAM. Also, while it can be difficult to work with more traditional art styles such as oil painting or gouache styles, VTuber creators have been experimenting with these styles with success.[20]
The first application of the Live2D technique is HibikiDokei released by sandwichproject (株式会社レジストプランニング), an alarm app released in 2010. The alarm app has a girl character named "Hibiki" who talks and moves.[21]
In 2011, Live2D adopted PSP game Ore no Imōto ga Konna ni Kawaii Wake ga Nai Portable released by NAMCO BANDAI Games Inc became the first game the O.I.U system derived from Live2D technology was applied in a game, where the character moves and changes positions and expression while talking to the player.[22] Characters moved expressively on the screen and seamlessly like an anime, which surprised players and triggered the popularity of Live2D.[23]

Software developer Tetsuya Nakashiro had been independently developing Live2D software and founded the company Cyber Noise (or Cybernoids, Japanese:サイバーノイズ) in 2006 with support from the Exploratory IT Human Resources Project of the Japanese Information Technology Promotion Agency (IPA). Because of its novelty and lack of uptake, Cyber Noise was unsuccessful.
In 2011, Live2D software received attention after its use in the PSP game Ore no Imōto ga Konna ni Kawaii Wake ga Nai Portable. It subsequently received interest as a library for Android and iOS. Following this success, in 2014 Cyber Noise subsequently renamed itself to Live2D Ltd.,[24] unifying with its product name. Sales of Live2D have had significant growth since then. In 2021, 70% of Live2D Cubism Pro users are or create Vtubers, followed by games/app developers and animation/video creators.[25]
Live2D Ltd. provides its software and SDKs under both commercial licenses and as freeware.
