| Abstract: | In order to solve the problem of generating oval curve,a study is made through the use of geometric transformation.Ellipse is used as the initial curve of the transformation that is made according to some given conditions.A means of generating oval curve has been worked out in this paper,and its forming process is also discussed,besides,a corresponding mathematical equation is created.The meanings of each parameter and the features of the curve in the equation are analyzed in great detail.Programming and verification are done based on the created mathematical equation.The results show that the drawing tallies well with the analysis. |
