properties. Where available, a fragment shader (also called Pixel Shader) is run in the rastering step for each fragment of the object. If a fragment is visible, it can now be mixed with already existing color values in the image if transparency or multi-sampling is used. In this step, one or more fragments become a pixel.

To prevent the user from seeing the gradual rasterization of the primitives, double buffering takes place. The rasterization is carried
