Fill-Area Primitives ●Fill( Filled)Area An area filled with some solid color or pattern To describe the surfaces of solid objects Most graphics library routines don t support arbitrary fill shapes A fill area is required to be specified as a polygon A set of polygon facets can approximate a curved surface(a polygon mesh), which can be called as SurfaceTessellationFill-Area Primitives  Fill (Filled)Area  An area filled with some solid color orpattern  To describe the surfaces of solid objects  Most graphics library routines don’t support arbitrary fill shapes.  A fill area is required to be specified as a polygon.  A set of polygon facets can approximate a curved surface (a polygon mesh),which can be called as SurfaceTessellation. 5
