Re: On Bezier Curves and analemmae

David,   Of course I know an analemma is not a analytical, closed-defined, blah, blah, blah curve, that's why I talk about worst-case approximation (control engineers call it H-infinity norm, sorry about the tecnicism), but we could as well define an H-2 norm (ie, the classical least squares) or some other you can imagine.   The stem of my question was: in order to save computing resources, which is the minimum number of dots we need to draw these curves with enough accuracy?   Anselmo   Dear Anselmo,   There is quite a difference between the mathematically well defined straight line and hyperbola and the real-world analemmae.  The latter is not a classical mathematical shape.   David
