+// Highly polished metallic surfaces such as copper or aluminum usually have an emissivity below 0.10.
+// Roughened or oxidized metallic surfaces will have a much higher emissivity
+// (0.6 or greater depending on the surface condition and the amount of oxidation).
+// Most flat-finish paints are around 0.90, while human skin and water are about 0.98.
