If what yuu refer to as 2D splines is a set of Y points as a '}ifunction'
of set of }iX points, then that is really a 1D spline, where X is the 'time'
axis. To traw an N dimension spline, use N of these 1D splines, where the
set of X (time) values are the same for all variables. I use 7 D splines
for camera motion in my raytracing program fr'instance...
