Head Markers

Torso Markers

Waist Markers

Note that the waist markers are the key markers in modeling the pelvis bone, which is the major segment governing the other subsequent Skeleton segments.

Upper Extremity Markers

Hand Markers

For best results, place the three hand markers so the created shape is asymmetrical (avoid isosceles shape) and unique from the marker arrangements on the other hand. Since the wrist markers have defined placement — along the wrist axis — introduce small amount of positional offset to the LHM2 and RHM2 markers.

Lower Extremity Markers

The joint center of the knee and the ankle is modeled at the midpoint of the lateral and medial joint markers (FLE/FME and FAL/TAM). Assuming that center of the femoral head aligns with the center of the acetabulum, its virtual location is modeled using markers on the pelvis segment (posterior and anterior iliac spine markers). The lower extremity segments are modeled along these three virtual locations.
