Is it okay to use 1D smoothing code for 2D path smoothing?

Hi,
I am trying to smooth a path defined in 2d by (x,y) which varies in time. I am using the Numerical Recipes 1d smoothing C code functions savgol() and convlv() to smooth x and y independently, which seem to do a pretty good job. However, while it seems to work, I was wondering if I should truly being smoothing these variables independently. Note, I have found several source for Sav. Gol. 2d smoothing image smoothing, but that is not what I am looking for. Just smoothing of a path defined in x and y, which varies in time.

Is this an OK approach?Yes, you can use the same numerical methods for smoothing a path in 2D as for 1D. The key is to make sure that your smoothing algorithm takes into account the relationship between the two variables. You may need to adjust the parameters of your algorithm to ensure that the two variables are treated equally. Additionally, you should consider any additional constraints that you have on the smoothed path, such as the maximum allowable curvature or the minimum allowable distance between points.
