I want to create a curve passing throw 3 points and I know the direction of the tangent on those point.
I try GeomAPI_Interpolate. I set the 3 points with their tangent and use the lagrange scaling argument to compute the lenght of those tangents.
Finally , I obtained a Curve with has two bump but I want a curve which is between a half circle, and a parabolla
How must I compute the lenght of my tangengy to obtain the good result ?
