Shaders are usually small programs, which allow us to take over control of certain stages in the rendering process to define the way how a scene should be rendered by the graphics processor. In consequence, shaders are an important building block in today's computer graphics and are also an extremely powerful tool to create all sorts of (special) effects that would be very hard to realize otherwise. For the sake of simplicity, we will only discuss vertex and fragment shaders here.


Fragment shaders are also called pixel shaders. Unfortunately, ...
