A client has asked me to implement the process for creating airfoils shown here -
He also requested that I need to be able to match existing airfoil point data as close as possible. I created a test Grasshopper program that allows me to adjust a Bezier curve by modifying the start and end tangent vector lengths and the angle of the start tangent vector in order to approximate the point set. I also set it up to limit the length of the tangent vectors to prevent the curve from overshooting the end points.
What I need help with is a method to automate adjusting the tangent inputs to fit a set of points. I can do this manually, which is why I added a RMSE calculation, but it is basically just guessing at which inputs I need to modify.
I looked at both Hoopsnake and Anemone to see if they would be helpful and really got nowhere with that approach.
Any ideas or suggestions would be appreciated.
