A polygon results from a polygon Begin / End object, a triangle resulting from a triangle strip, triangle fan, or series of separate triangles, or a quadrilateral arising from a quadrilateral strip, series of separate quadrilaterals, or a Rect command. Like points and line segments, polygon rasterization is controlled by several variables. Polygon antialiasing is controlled with Enable and Disable with the symbolic constant POLYGON_SMOOTH. The analog to line segment stippling for polygons is polygon stippling, described below.
