Abstract Text:
Visualizing three-dimensional (3D) data can be extremely useful for understanding physical phenomena and can lead to physical insight. Another application of visualization is to allow one to see "invisible" physical phenomena, such as magnetic fields and magnetic field lines. ​But, a practical, easy-to-use, and cheap method of achieving fully 3D visualization is ​difficult. As a consequence, 3D phenomena are often reduced to 2D representations. For example, in stellarators the magnetic field is often visualized as a one-dimensional loop in two-dimensional cross sections, rather than nested contours in their full three dimensions. Recent breakthroughs in Augmented Reality, however, enable the community to visualize AR graphics using hardware readily available in any modern cellphone.

Augmented Reality can create unprecedentedly visual solutions to problems in fusion science. To illustrate, we will demonstrate: 1) the visualization of any Fusion Design CAD in holographic 3D by utilizing a flat AR tracker, 2) the measurement of “live” magnetic field lines and their superposition over a real experiment, by combining AR tracking with the magnetometer on board most smartphones, and 3) visualization of Stellarator coils, magnetic field contours, and single particle orbits in room filling 3D which one can walk through, using a Hololens system with IR tracking.
