-- An offset curve is a curve at constant distance (Offset) from
-- a basis curve in a reference direction V. The offset curve
-- takes its parametrization from the basis curve.
-- The Offset curve is in the direction of of the normal N
-- defined with the cross product V^T where the vector T
-- The Offset curve is in the direction of the normal N
-- defined with the cross product T^V, where the vector T
-- is given by the first derivative on the basis curve with
-- non zero length.
-- The distance offset may be positive or negative to indicate the
-- preferred side of the curve :
-- . distance offset >0 => the curve is in the direction of N
-- . distance offset >0 => the curve is in the direction of - N
-- . distance offset <0 => the curve is in the direction of - N

-- On the Offset curve :
-- Value (U) = BasisCurve.Value(U) + (Offset * (T ^ V)) / ||T ^ V||
