2025年3月26日 · For gemologists, refractive index and double refraction (birefringence) serve as important clues for identifying gems. The following table lists these values for a variety of …

Index of Refraction IOR values - For use with 3d modeling / rendering and animation applications

Refractive index, or RI is one of the most important signatures of a gemstone. Measuring the refractive index is one of the first steps in identifying a gemstone, though some gems have similar refractive indices and additional tests are required for a definitive identification.

L - Materials Labradorite 拉长石、拉布拉多岩 1.560 ~ 1.572 Lapis Gem 拉皮斯宝石 1.500 Lapis Lazuli 拉皮斯青金石、琉璃 1.500 ~ 1.550 Lazulite 天青石 1.615 Lead 铅 2.010 Lead Nitrate 亚硝酸铅 1.782 Leucite 白榴石 1.509 Light Flint Glass 薄火石玻璃 1.575 Liquid Carbon Dioxide 液态二氧化碳 1.200 Liquid ...

IOR定义材质折射率:设置透明材质的折射率。 它表示光在介质中传播时，介质对光的一种特征。 一些常见材质的IOR (折射率): 玻璃: 1.517 钻石: 2. 417 绿宝石: 1.57 蓝 (红)宝石:1.77 翡翠: 1.4 黄金: 0. 47 水: 1.318…

2022年7月25日 · 如果您知道要了解正确 IOR 值是什么，那么这显然是有帮助的。 那么支持的常用 3D 程序如下，如 NewTek Lightwave 3d、Blender 3d、Autodesk 3DS Max、Autodesk Maya、Autodesk Softimage、Maxon Cinema 4D、Next Limit Maxwell、Foundry Modo 和 Strata 3d。

2020年5月7日 · 以下是我找到的 用于常见材质3D渲染 的 IOR(Index Of Refraction, 折射率)值。 现在的许多 3D应用程序 允许输入实际的 IOR值，以便在绘制 3D 模型时实现对表面的更准确表示。

Refractive index (or R.I.) is a measure of how much light is slowed/bent as it passes through a material. A higher value, or more 'bending power' means greater ability for the gem, with proper cutting, to re-route light back out to the observer rather than passing through the gem to the backside, and thus creating more total brilliance.
