How do you draw a filled polygon in OpenGL?
By default OpenGL draws polygons in fill mode by filling in all the pixels enclosed within the boundary, but they can also be drawn in line mode as outlined polygons, or in point mode as points at the vertices. In OpenGL a polygon has a front and a back side.
