WebOver the years I have been collecting IOR (Index of Refraction) values I can find for use in 3d rendering applications. Many 3d applications these days allow you to input … WebIndex of Refraction or IOR is an optical measurement that can be used to tell you exactly how much light will be bent when light propagates from one medium to another. Since this lighting phenomenon can be measured, we can use these measurements inside UE4 to affect how the Refraction will look giving a better sense of realism to our 3D world.

Web13 okt. 2024 · A real-valued index of refraction is used to describe a material that is an insulator, typically a dielectric. Reflection from a conductor, such as a metal, is not the same as reflection from a dielectric. The intensity and polarization of the reflection are different. A conductor cannot be described by a real-valued index of refraction. WebWhat is IOR? Why do we need it?
