Hi,
I wonder if it is possible to come up with a F-spline curve that is exactly the same as a circle? Ideally this circle can be represented by 5 points with starting point and end_point overlapped with each other. The optimization I would like to do is to move p1 and p3 in x-direction, while the tangential direction at P1 and P3 is kept horizontal, and keep the area as constant.
Is F-spline the best option to achieve this? Would you help me to set up a quick example?
Best,
Zhen
