In 3D visualization, the IOR can be used to create materials that look realistic. For example, if you want to create a glass object, you would need to give it a high IOR so that light bends when it passes through the glass.

The IOR can also be used to create materials with special effects. For example, you can use a low IOR to make an object appear transparent, or you can use a high IOR to make an object appear like it’s made of metal.

Index of refraction is an important concept in 3D visualization because it helps us create realistic looking materials. It’s also a lot of fun to play around with IOR values to see what different effects you can create.
