Specular reflection refers to the reflection of light off a surface in a way that highlights its shininess or smoothness. Unlike diffuse reflection, where light scatters in various directions, specular reflection creates a concentrated and mirror-like reflection. The appearance of specular reflection depends on the angle of the light source, the viewing angle, and the surface properties.
Visualize sunlight reflecting off a calm body of water – the specular reflection creates a bright, concentrated highlight on the water’s surface. In computer graphics and 3D rendering, simulating specular reflection is crucial for achieving realistic and visually appealing materials, such as metals or glossy surfaces. Understanding and controlling specular reflection adds a layer of sophistication to the depiction of materials in virtual environments.
