Cheetah 3D: using hierarchy for animation
We will create an arm, composed of two bones and one joint.
- Bones will be materialized using cylinders.
- The joint will be materialized using a ball.
The bones
- The humerus (from the shoulder to the elbow).
- The ulna (from the elbow to the wrist).
The joint
- The elbow
The important point is that Cheetah's joints are not used.
WARNING! The important thing is the hierarchy between the three elements. The humerus is "parent" of the elbow. The elbow is "parent" of the ulna.
Now you can bend the elbow
