Harthong-Reeb analysis and digital circles

Abstract: We present a new approach to derive efficient and precise algorithms of interest to computer graphics. This is illustrated here by the case of the circle. It also yields algorithms for straight lines and more infrequent curves, such as segments of exponentials. The method is, in essence, the numerical integration of vector fields using only integers.

“…The general idea of the arithmetization method [14,15] is to transform this continuous numerical scheme into a discrete one with only integer variables. This discrete scheme generates a digital planar curve C d (0, R) which is a discrete analog of the circle C(0, R).…”

“…Este desplazamiento tiene la ventaja de ser siempre fijo y conocido con antelación [HOLIN91]. En caso de realizar esta operación por hardware, el desplazamiento de la mantisa tiene un coste computacional nulo, por lo que en la práctica, su coste global puede considerarse idéntico al de cualquier operación entera [COLLA79].…”
