Double-stance- The phase of a walk during which both feet are in contact with the ground.


Figure A-4 shows the phases of a bipedal walk.


Single-stance- The phase of a walk or run during which only one foot is in contact with


the ground. See Figure A-4.

Computer Animation


Motion capture- A technique, used to animate computer generated characters, in which the


motion of the animated character is taken from a real world source such as a person

walking.

Modern forms of motion capture typically use markers attached to the

subject's body which are tracked by a sensing device (e.g. an IR camera).


Rotoscoping- A form of motion capture in which motion data is taken from pre-recorded


live images such as film or video.

Pose Control Graph (PCG)- A type of finite state machine which specifies a set of


desired poses over time. Each desired pose specifies a set of desired joint angles for

the articulated figure being animated.
