What is Refraction Index?

Refraction Index is a measure of how light bends when it passes through a medium. The higher the refraction index, the more the light will bend. This is important for 3D artists because it allows them to create realistic looking objects by simulating the way light interacts with them.

The refraction index of a material can be affected by its composition, temperature, and pressure. For example, glass has a higher refraction index than air, so light will bend more when it passes through glass than when it passes through air. Similarly, hot water has a higher refraction index than cold water, so light will bend more when it passes through hot water than when it passes through cold water.
