In graphics processing, a computer program called a shader takes the lead in executing rendering effects with flexibility and precision. The term was originally coined for shading, the production of perfect levels of light and color within an image. Now shaders serve various purposes, ranging from video post-processing to specialized tasks in graphics effects or functions entirely unrelated to images. Shaders on modern hardware, mainly run by graphics processing units (GPUs), excel in calculations with ease due to their high flexibility. Though most are coded for GPUs, it's not a necessary requirement, and other types of processors can also be utilized. Typically, the GPU rendering pipeline is used through a specific shading language that has mostly replaced fixed-function pipelines. Programs use algorithms in shaders to change color properties such as hue, saturation, brightness, and contrast instantly, or modify effects through variables and textures inserted by external sources. The graphics engine then utilizes these calculations for an accurate display on the final output screen. In modern filmmaking and gaming applications, a vast range of unique visuals are made possible through the integration of this versatile technique. In computer-aided rendering and high-fidelity games, users frequently utilize specialized effects created using shaders that not only change appearance by enhancing brightness but can even perform blur and depth mapping on scenes, to achieve distinctive features. For example, producing motion blur that blurs elements on screen quickly, changing the texture for objects from 3D mesh geometry into detailed surfaces of a given object in your scene. This term was introduced to the public through Pixar with version 3.0 of their RenderMan Interface Specification initially published in May 1988, before spreading its use in computer-aided animation to include modern game and graphic production for various effects.
