Filled-Area Primitives
Filled-area primitives are one of the most important types of primitives used in Computer Graphics. Basically filled-area primitives are meant to fill the given bounded and closed region with a single color/multiple colors or with some fill pattern. You will find later that almost all types of curves/surfaces are approximated by polylines/polygonal surfaces for the purposes of scan conversion. Therefore, polygon fill algorithms are extensively used in applications involved in 2D geometry processing or, in scan converting surface patches with polygonal surface approximation. This section deals with some of the important and most common algorithms being used for defining and implementing filled area primitives.
