Reflectivity of a material
WebThe substrate has a constant refractive index of 3.5 and approximates silicon. Under air, the reflection is minimized by setting the top layer to 105 nm with a refractive index of 1.4 and setting the bottom layer to 55 nm and a reflective index of 2.4. Click on the graph for numerical data. Web1. nov 2013 · The reflectivity has to come from objects in the scene. I havent seen any exampes of the desired effect. Something like a shiny plastic or metal. The reflection will be there that is a bit diffused, not like the mirror example. Although the mirror example is the closest example Ive seen. Can you pease provide some code to get me started? – MCSharp
