Rigging in 3D modeling is the process of creating a digital skeleton (armature) to control a 3D model’s movement, enabling animators to manipulate its motion.
This skeleton includes key joints (e.g., elbows, knees, or facial bones) that act as control points. The rig connects the model’s geometry to these joints, translating animator inputs into realistic movements—such as walking, jumping, or facial expressions.
Common applications span animation (cartoons), gaming (character actions), and film (realistic character motion). For beginners, starting with simple rigs (e.g., a basic human armature) helps grasp how movement is enabled.
