Rigs and bones contribute to 3D character animation by forming a hierarchical control system that links the model’s mesh to an underlying skeletal structure, enabling precise, lifelike movement manipulation.
Bones replicate the character’s skeleton, with joints (e.g., elbows, knees) allowing natural bending and rotation—this mimics real anatomy, serving as the foundation for authentic motion.
Rigs act as the animator’s interface, translating bone adjustments into mesh movement. When a bone is moved, the attached mesh follows, making it possible to create fluid animations (walking, gesturing, facial expressions) by controlling key skeletal points.
