A character’s skeleton drives the character’s motion. The skeleton captures geometry and controls the geometry’s deformation.

To create skeletons in Houdini you work with bones (unlike some other 3D packages where the focus is on joints) at the object level . Each bone has an orientation and a length that define its shape. The bone’s position is generally determined by its parent. The bone’s orientation is relative to the parent, so rotations start at (0, 0, 0).
