Hi Jesse - I see what you mean.

The part that is confusing here is the "automatic deformable points" feature.

This is what makes a degree 2 sphere that is made up of 4 quadrants instead show the control points of a deformable degree 3 surface approximation. The sphere is actually degree 2 the whole time but if you move one of the points, it will get automatically converted into a rebuilt degree 3 surface approximation so that it can be squished smoothly (you have probably already seen the kind of quadrant segmentation that happens if you move the points on a degree 2 surface that has fully multiple knots in it).

This automatic refitting is only active for surfaces of revolution. If you scale a sphere in the direction that its seam is running, it will remain a surface of revolution, but if you scale it along one of the other directions it will no longer be a surface of revolution and won't have the automatic refitting applied to it.

I think it may be possible to me to extend this to work better in the future instead of only working on surfaces of revolution.
