The process further identifies a spine segment, generates hip, shoulder, and head segments at respective positions relative to the spine segment, identifies limb and facial feature segments, and converts the segments into respective splines bound between endpoints. The process further determines changes between frames for respective splines and animates movement of the figure over a sequence of frames based on the changes.
