fractionToPointAnd2Derivatives Method
Construct a plane with
- origin at the fractional position along the arc
- x axis is the first derivative, i.e. tangent along the arc
- y axis is the second derivative, i.e. in the plane and on the center side of the tangent. If the arc is circular, the second derivative is directly towards the center
