Fresnel effect

A shading phenomenon where the amount of reflectivity on a surface changes based on the angle of view.In 3D rendering and shading, the Fresnel Effect is used to simulate this phenomenon, particularly for materials like glass, water, metals, and other reflective surfaces. By adjusting the reflectivity based on the angle of incidence (the angle between the viewer and the surface), the Fresnel Effect helps create more realistic and dynamic surfaces.
