What is an 'armature' or 'skeleton rig' used for in product animation?
Answer: A system of bones used to deform and animate a product's mesh in a controlled, hierarchical way
An armature is a hierarchical system of bones that deforms the product mesh, enabling precise control of moving parts like hinges, flaps, or articulated components.
What is the difference between IK (Inverse Kinematics) and FK (Forward Kinematics) in product rigging?
Answer: IK positions a chain's end effector and calculates joints backward; FK rotates each joint forward from the root to the tip
IK allows animators to place the endpoint (e.g., a lid) and let the rig solve intermediate joints automatically, while FK requires rotating each joint in the chain manually.
What is a 'constraint' in 3D animation rigging and how is it used in product animation?
Answer: A rule that controls one object's position, rotation, or scale relative to another object
Constraints automate relationships between objects — for example, making a product lid always track the hinge point, or a label always face the camera regardless of product rotation.
What is 'follow-through' as an animation principle, and how is it applied when animating product packaging?
Answer: The continuation of loose or secondary elements after the main object stops, like a ribbon or tag swaying after a box lands
Follow-through means flexible parts (ribbons, labels, hanging tags) continue moving and settle naturally after the primary product stops, adding physical believability.
What does 'secondary animation' mean in the context of 3D product animation?
Answer: Subtle supporting motion added to elements that react to or accompany the main product movement
Secondary animation refers to supplemental movement — like a liquid sloshing inside a bottle as it moves, or dust particles disturbed by a product hitting a surface — that enriches believability.
In product animation, what is a 'driven key' (or driver) used for?
Answer: A relationship that uses one object's property to automatically drive another's animation value
A driven key (driver) links one parameter to another — such as using a product door's rotation to automatically drive the hinge creak sound or a secondary panel's movement.
