Pixel shader

A pixel shader is a type of colour manipulator used to lighten or darken pixels on a two-dimensional texturemap in real time. It does this to give the visual illusion that parts of the image are casting shadows, or in full light. By changing the shaded areas over time in response to stimuli, the effect of a 3D surface without the additional rendering of a 3D surface is created.

Pixel shaders work per pixel, one at a time, across every point on the display screen. For larger display sizes approaching organic human vision levels, many millions of pixels must be calculated, each and every screen update.
