This example extends Example 1 to specify a spline interpolation method on the GRID statement. The output data set, when used in PROC G3D, generates a smoother surface plot than the surface plot that ...

It can also be useful to explore why cubic-spline interpolation is more appropriate for motion control than, say, interpolations involving higher order polynomials.

This example specifies a partial spline interpolation method on the GRID statement, using eight nearest neighbors for computing the estimates of the first and second derivatives. The output data set, ...
