What is material IOR?
The Index of Refraction (IOR) is a value used to specify the way that light is scattered as it passes through a material. Since we live on Earth, all IOR values assume that 1.0 is the value for traditional linear light behavior. And thus, air has an IOR of 1.0. Water has an IOR of 1.33.
What is the IOR of marble?
At 1.5 the object behind distorts greatly (like a glass marble). At an IOR slightly less than 1.0, the object reflects along its edges, like a bubble seen from under water. Default=1.5 (the IOR of typical glass)….Setting the Index of Refraction.
| Material | IOR Value |
|---|---|
| Air | 1.0003 |
| Water | 1.333 |
| Glass | 1.5 to 1.7 |
| Diamond | 2.418 |
What is Fresnel IOR?
Every material has a Fresnel value which is indicated by its index of refraction (IOR). This value shows how much of the ray is reflected off the surface versus how much is absorbed. Surfaces viewed at grazing angles reflect more of the incoming light compared to surfaces facing the camera.
What is marble onyx?
In marble. The so-called onyx marbles consist of concentric zones of calcite or aragonite deposited from cold-water solutions in caves and crevices and around the exits of springs. They are, in the strict sense, neither marble nor onyx, for true onyx is a banded chalcedony composed largely of silicon…
What does IOR mean in Maya?
The IOR parameter (Index of Refraction) defines the material’s Fresnel reflectivity and is by default the angular function used. Effectively the IOR will define the balance between reflections on surfaces facing the viewer and on surface edges.
