| Abstract: | This paper indroduces the algorithms for clipping lines,curves and polygons,including the recent research work of the authors.Firstly,to the rectangle window,algorithms for clipping lines,circles and ellipses,as well as parametric curves are introduced.Then,line clipping algorithms and polygon clipping algorithms against polygon windows as well as algorithms for"intersection","subtraction"and"addition"between regions are described.Finally line clipping algorithms against circles and ellipses are given. |
