I maintain that elliptical arcs do not need three on-curve points: two are enough for the on-curve points, plus only 1 off-curve control point (what I described) which is the intersection of the tangeants on the two starting and ending points. Read carefully... You forgot this control point which is easy to position (and this is also true for the full ellipse: you just need two points on the ellipse that are not diametrally opposed and a single point of intersection of their tangeants (that why I spoke about a possible but optional flag to indicate if we want the short or long arc between the two on-curve points, or the full ellipse, the default flag would just be the short arc (quite similar to a quadratic Bezier about the parametrization) ! -- GitHub Notification of comment by verdy-p Please view or discuss this issue at https://github.com/w3c/svgwg/issues/767#issuecomment-626231632 using your GitHub account
