3D cartoons are a form of stereoscopic animation that combines 3D modeling and animation technologies. They use computers to create virtual 3D characters and scenes, endowing them with colors, textures, and dynamic effects to transform flat images into three-dimensional ones (such as the characters in Toy Story). Breaking the limitations of traditional hand-drawing, they can present more delicate expressions, smooth movements, and immersive scenes. Widely used in animated films, games, children's programs, etc., they are both interesting and visually striking, and are popular among audiences of all ages.
