Baseline Lower Body (20) Placements[edit]

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. For best results, avoid placing the waist markers in a rectangle shape. When tracking multiple actors with similar proportions, introduce an offset to one of the WaistBack marker, or the WaistCMarker (included only with the 13 additional markerset), to create an asymmetrical arrangements.
Label Related Segment Description
WaistLFront Pelvis Placed the marker on the protruding bone located on the front of the pelvis (left/right anterior iliac spine bone). The prominence can be palpated from left and right side of the waist.
WaistRFront Pelvis
WaistLBack Pelvis Place the WaistLBack and WaistRBack markers above left/right hip; about 10 cm above the hip joint.
WaistRBack Pelvis
Leg Markers
Label Related Segment Description
LThighFront Upper Leg Place the marker on the front side of the thigh, along the midline. For best results, slightly offset the height of the left and right markers to introduce the asymmetry.
RThighFront Upper Leg
LKneeOut Upper Leg Place the marker on the outter prominence of the knee joint; on the lateral epicondyle of the femur. Palpate the knee for the protruding bone from the upper leg, and place it right on the axis. Ask the actor to flex and extend the knee few times to confirm that the markers are placed along the axis and maintain stationary throughout the range of motion cycles.
RKneeOut Upper Leg
LShin Lower Leg Place the marker on the shin bone; on the midline of the lower leg. For best results, slightly offset the height of the left and right markers to introduce the asymmetry.
RShin Lower Leg
Foot Markers
Label Related Segment Description
LAnkleOut Lower Leg/Foot Place the marker on the protruding bone outside of the ankle joint; on the lateral end of the malleolus bone.
RAnkleOut Lower Leg/Foot
LToeOut Foot Place the marker just before the little toe joint; on the distal end of the fifth metatarsal bone.
RToeOut Foot
LToeIn Foot Place the marker just before the big toe joint; on the distal end of the first metatarsal bone.
RToeIn Foot
Hinged Toe Markers
Hinged toe markersets create toe segments in the skeleton. Two additional markers are added to each foot, one on the toe-tip and another on the heel. The hinged toe markers are included in all baseline markersets except for Baseline (37) and Upper Body markersets.
Label Related Segment Description
LHeel Foot Place at the center of the heel.
RHeel Foot
LToeTip Toe Place the marker on the tip of the second toe; next to the big toe.
