Andy is right. The recursive subdivision doesn't work correctly -- it produces pairs of equal sides, but those pairs don't necessarily equal pairs futher away. Back to the drawing board... At 02:37 PM 11/18/2010, Andy Latto wrote:

[My statement below about "notchy" is *wrong*. Given an ellipse, you can start my recursive perpendicular bisector subdivision from _any_ line through the center of the ellipse.
But as someone pointed out, the recursive perpendicular bisector subdivsion doesn't work. You replace side AB with sides AC and CB, where |AC| = |CB|, and you replace side XY with sides XZ and ZY, with |XZ| = |ZY|, but there's no reason to expect that just because |AB| = |XY|, that |AC| should equal |XZ|.
