Over 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 actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models.

Nov 3, 2017 · Index of Refraction values (IOR) To create realistic PBR Materials for use in 3D Applications you will need the right Fresnel or IOR Factor in order to achieve a more accurate representation of a surface material.

Looking to make your 3D materials photorealistic? Discover the ultimate database of IOR and Abbe numbers for 3D rendering accuracy. Improve your shaders by setting precise Index of Refraction values.

Index of refraction of any material is strongly dependent on the wavelength (frequency) of light used to measure it. Standard index of refraction measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers (509 THz).

These IOR values are taken from the great resource RefractiveIndex.INFO, but it only includes the values relevant for setting up materials for physically based rendering. The values listed here should work with several different rendering engines, such as Octane Render and Arnold.

Sep 5, 2022 · What Is IOR (Index of Refraction)? IOR, in short, is a number that tells you how much and what direction light bends when going through a medium (E.g. glass). For most rendering application needs: lower IOR values equal …
