====== Tracker Placement ======

DEMoCap supports various setups for tracker placement. While calibrating DEMoCap assigns the trackers placed on the body to the closest tracker slot of matching type. The motion transfers then take care of mapping the tracker slot to the respective origin and character tracking slots. For this reason you can freely orientate the trackers on the body to fit best the requirements of the capture session at hand. For laser driven trackers a clear line of sight to the base stations ensures best tracking results. For this reason it is best to wear waist and chest trackers on the back. Depending on the situation you might have to move them front side for example if the actor has to perform while sitting on chair. For computer vision based trackers bright light conditions ensure best tracking results. For magnetic based trackers avoiding interfering materials ensures best tracking results.

The 3D view below shows the recommended setup if a full set of 11 laser trackers is used. Click image or link to open 3D model in SketchFab.
