Live2D is a technology that allows 2D illustrations to be animated in a way that gives them a three-dimensional appearance. It enables artists to create dynamic characters that can move, express emotions, and interact with users while maintaining the original 2D art style. This is particularly popular in video games, virtual YouTubers, and interactive media. The process involves breaking down a 2D image into separate parts, such as eyes, mouth, and limbs, which can then be manipulated independently. Live2D software, like Live2D Cubism, provides tools for rigging and animating these components, making it accessible for both professional and amateur creators.
