It is also possible to also zoom and pan. +A scroll bar that controls the material density allows the user to interactively investigate how different densities affect the refractive index. + +It also provides functionality for the differential refractive index (the refractive index for the boundary when you have a material inside another material). + +[1] http://henke.lbl.gov/optical_constants/getdb2.html +[2] B.
