STREAMLINE VISUALIZATION: Electromagnetic trackers, used by motion and virtual reality applications, are notorious for their sensitivity to magnetic field distortions, typically caused by metal objects or electronic equipment in the surrounding environment. Creating so-called "streamline" visualization, based on measurements from magnetic calibration equipment, shows how the tracker will be affected at various locations. Here, the shape of the lines indicates the direction of the magnetic distortion, and the color indicates the magnitude, with the red lines depicting areas where tracking error is highest, ...
