In 3D animation, the motion of one part can affect the motion of other parts, creating a follow-through and overlapping action. This means that some parts will lag and overlap with the main motion, resulting in a smooth and natural effect. Follow-through and overlapping action can be shown in these ways:
- The motion of accessories: For example, long hair, tail, cape, etc. These parts will keep moving after the main motion stops, creating an effect of inertia and elasticity. This effect can be achieved by changing the position and angle of the accessories in each frame, or by using hair and cloth systems in animation software.
- The motion of the body: For example, waist, arms, head, etc. These parts will stretch and squash each other when the main motion happens, creating an effect of force transfer and rhythm. This effect can be learned by watching videos or pictures of real people or other characters, or by using skeleton and muscle systems in animation software.
