![]() Most shaders are coded for (and run on) a graphics processing unit (GPU), though this is not a strict requirement. Traditional shaders calculate rendering effects on graphics hardware with a high degree of flexibility. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing, as well as general-purpose computing on graphics processing units. In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene - a process known as shading. This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture. The unaltered, unshaded image is on the left, and the same image has a shader applied on the right. Another use of shaders is for special effects, even on 2D images, (e.g., a photo from a webcam).
