Modulated Ellipse

This is an ellipse with the earlier spline modulated onto it, once again using the even spacing already developed.

 

Note that although the vanilla spline has c1 continuity, there is a lack of c1 continuity here - this is because the colinear control points for adjacent Beziers are being evaluated at different points on the ellipse, with different normals.

 

This will be fixed in another iteration.
