3D animal characters are virtual animal images created using digital technologies such as 3D modeling, rendering, and animation, and are widely used in fields like animation, games, film and television, advertising, and popular science education. Their core lies in building 3D models of animals through professional software (e.g., Maya, Blender, ZBrush). Every detail—from skeletal structure and muscle alignment to fur texture and skin quality—can either be recreated based on the characteristics of real animals or redesigned in an anthropomorphic or fantasy style. For example, animals may be given human-like facial expressions, or fantasy elements may be added (such as lions with wings or glowing deer).
