In addition to the test object, the bow shock and turbulence are clearly visible. How is this visualization accomplished? Is the medium air, or a denser fluid such as water? Is there a pigment added to the fluid to help visualization? Is there special lighting, such as polarized light? Any notable camera tricks? Is the 3-D nature of the test object more significant than being a thick 2-D object? ...
