fractionToPointAnd2Derivatives MethodAbstract

Return a plane with

• origin at fractional position along the curve
• vectorU is the first derivative, i.e. tangent vector with length equal to the rate of change with respect to the fraction.
• vectorV is the second derivative, i.e. derivative of vectorU which points in the direction of the curve's derivative's change.
• Note: We are dealing with a parametric equation of the curve (a function f : R -> R^3) so first and second derivatives are in fact derivatives of the parametric equation.
