What is Refraction?
When it comes to 3D visualization, refraction is an important phenomenon to keep in mind. Refraction occurs when light waves travel through a medium and bend due to the change in speed. This change in speed can be due to the different densities of the mediums involved. For example, when light waves travel from air into water, they bend because the water is denser than air. The amount of bending that occurs depends on the difference in density between the two mediums.
In 3D visualization, refraction can create some interesting effects. For example, when light waves bend as they pass through a medium, they can cause objects to appear distorted or even magnified. This can be used to create some interesting optical illusions. Additionally, refraction can be used to create special effects like light rays that appear to bend around an object.
