WebThe unit principal normal vector and curvature for implicit curves can be obtained as follows. For the planar curve the normal vector can be deduced by combining ( 2.14) … WebThe Normal and Binormal Vectors At a given point on a smooth space curve r(t), there are many vectors that are orthogonal to the unit tangent vector T(t). We single out one by observing that, because T(t) = 1 for all t, we have T(t) T'(t) = 0, so T'(t) is orthogonal to T(t). Note that T'(t) is itself not a unit vector.
