Interesting contrast to this is that most modern vector 2D graphics API use PostScript/PDF drawing model that cannot represent exact circles and elipses and these are instead interpolated by a bunch of bezier curve segments.

Heh, this would have been super helpful last summer as were nearing completion on the construction of our new home. We have an elliptical arch in our front portico that the carpenter was having trouble getting right...

Don't these ovals suffer from the problems of g1 continuity, like for example ugly reflections if such an oval is made into a 3D reflective object? The reflections getting suddenly tighter where arcs connect. Or is it not noticeable if enough arcs are used?

Why is it that a constant curvature is preferable for a builder? Is it that construction forms etc are fabricated basically by compass and straightedge still?

Did I miss where an actual oval is explained in this method? I assume it is just drawing the same arc upside down but wanted to be sure there isn’t a follow up post or something.
