 To track a segment, a minimum of three noncolinear targets are required.

+=== Spread Out Tracking Targets ===
 If the targets are spread out over the segment:\\

+{{:ClusterSize_Large_Segment.png}}\\
 It takes a large amount of target movement to produce a large change in the position and orientation of the segment:\\

-==== Application ====
+=== Application ===
 The closer the targets are together, the more susceptible the tracking will be to noise. So try to use best judgement when placing markers/defining clusters.
 This is true for tracking any segment, but it tends to be most relevant when tracking the pelvis (using a small cluster on the lower back vs using the ASIS and PSIS) or tracking the foot (using a heel cluster vs heel and met targets).
