| Abstract: | Graphics clipping and covering is one of the key points in computer graphics field. Alter more study and practice.a new algorithm is give.which is for clipping and covering in circular window.Adopting shilling principle to do multiply and division operation.we have got a more speed in clipping and covering.raised the capability of computer in graphics processing. |
