fragment shaders

Fragment shaders are small programs used in computer graphics to determine the final color and appearance of each pixel on a screen. When a 3D scene is rendered, these shaders calculate how light, textures, and colors interact at every pixel, enabling realistic rendering of surfaces like skin, water, or metal. They run on the graphics processing unit (GPU) and help create detailed, vibrant visuals by dynamically producing colors based on lighting and material properties. In essence, fragment shaders control the visual details of every pixel, contributing to the realism and style of digital images.
