Tracks are displayed as a sequence of a small squares at the CoG for all geometric objects that comprise the track. Each square is orientated as the object it represents.

Optionally, tracks can be displayed with connecting straight lines or cubic lines. Squares and lines are colored in relation to the track color.

A track is not displayed fully. A track is displayed a specified number of frames in the past and in the future. To the end of the track, squares become gradually more transparent.
