【Abstract】 Methods for testing the scale factors and rapid clipping graphics on screen are proposed in this paper. The algorithm and program are simple and can easily be realized.By these methods, it takes less time. Therefore, the methods are of practical significance for computer display in CG and CAD. The methods discussed in this paper have been applied with HITACHI 16000A and IBM—PC. The results are desirable. The methods proposed in this paper are also available to plotter更多还原
