Describe and explain different polygon formats.
The graphics package determines how the polygon is represented in the system. There are three techniques to representing the polygon: Polygon drawing primitive approach: Some graphics packages offer polygon as a fundamental image shape; in this case, the polygon is represented as a whole entity. Such polygons render quickly. Trapezoid primitive approach: In certain graphics programs, a polygon is approximated as a series of trapezoid primitives. Line and point approach: The polygon in this approach is defined by end point coordinates. To form the polygon, a line is generated between each end point.
