What is the Fresnel Effect in Blender?

The Fresnel Effect in Blender is a shading technique that changes the appearance of a surface based on the angle of view relative to the surface normal. This effect is commonly used to simulate how light reflects differently on surfaces depending on the viewing angle, creating more realistic and dynamic materials, particularly in transparent or reflective objects.

Use Cases in Blender

• Realistic Materials: The Fresnel Effect is crucial in rendering realistic materials like glass, water, and metal, where the reflectivity changes with the angle of incidence.

• Special Effects: In visual effects, the Fresnel Effect is used to enhance the appearance of dynamic materials, such as glowing energy fields or holograms.

• Architectural Visualization: The Fresnel Effect helps in rendering windows, mirrors, and other reflective surfaces accurately in architectural renders.
