Difference method for generation of circular arcs and ellipses
This paper presents a method called difference method that generates the vertices of the inscribed polygon of a circular arc or an elliptic arc. The author emphasizes that only two multiplications are needed with this algorithm to compute one vertex of the polygon, such that it is therefore more efficient than the matrix method. In the analysis of the error propagation it is proved that the difference method is stable. Finally, numerical examples and suggestions for further extensions of the difference method are provided.
