Introduction page of the log-aesthetic curve, here is. Past research here is.

The following is an introduction to the main content of relatively recent research.

· 3D Class A Bezier Curves

elucidation of the nature of the space curve control and interactive class A Bezier. interactive control is realized by efficient to clarify the geometric properties of space curves with class A Bezier, to take advantage of it.
