To make the curvature continuous, there is an option within the Tangent relation. First click the Tangent tool from the ribbon, then on the Command Bar, click the Type dropdown, and select Tangent + Equal Curvature. Notice now that the curvature combs from the two different splines match in magnitude at their mutual end.

Cubic Spline Mimicking the form of the piecewise linear interpolant, in this case we require that on each subinterval [x i,x i+1] the piecewise interpolant s satisfies s(x) = s i(x) = a i +b i(x−x i)+c i(x−x i)2 +d i(x−x i)3, where a i,b i,c i, and d i are coefficients to be determined.

Note how the 3 spline interpolations are performed in a single call to spline().This works, because we duplicated the measurement values in V three times and individual spline interpolations are performed on the 3 columns of V.The only distinction for the individual splines is done in the lbDeriv parameter. Here, a vector is provided with 3 elements.

Basis splines are just a type of spline formation. Splines can look different depending on which type you use. This makes sense — there are many different ways to form a line through data points. Take this image for example: source. Each colored line is a different type of spline. The red line is a type of basis spline!

Generates a spline along several points. The amount and locations of these points may be arbitrary or gathered from a Point List node. The trajectory of the spline can be smoothed away from its intermediary points, in that each intermediary point is the meeting point of the 'out' and 'in' tangents of its neighbours.

B-splines have d + K, while a natural cubic spline basis function with K knots has K +1 degrees of freedom, respectively. By default, the function bs in R creates B-splines of degree 3 with no interior knots and boundary knots defined at the range of the X variable. As such the function creates three basis functions.
