3D cartoons are a visual form that integrates 3D digital technology with cartoon art styles. With the help of modeling software, they construct three-dimensional characters and scenes. Through technologies such as skeletal binding and material rendering, they endow the images with realistic light and shadow layers and spatial depth, breaking through the flat limitations of traditional 2D cartoons.

Their character designs mostly adopt rounded outlines, exaggerated proportions and bright colors, retaining the cute characteristics of cartoons. At the same time, 3D technology enables delicate body movements and facial expressions, making virtual images more vibrant. They are widely used in animated films, children's education, interactive games and other fields. For example, the Toy Story series not only conveys innocence with cartoon styles, but also creates an immersive fantasy world through 3D effects.
