digitized point smoothing algorithm

Gentlemen,

One more question about digitizing. (Maybe I am provoking a little more digitizing chatter)

After I obtain a string of x,y points from digitizing, I would like to be able to produce some smooth curves between the points, without using a whole cad program to do so. Does anyone know of some source code which would allow me to take my digitized list of points in an ascii file and run them through an algorithm that would produce intermediate points and a slight smoothing effect on the digitized points? I realize that I am being very subjective in this, as I haven't said how much smoothing I want, but I would like to be able to fool around with some different values and select an appropriate amount of smoothing effect.

I realize this is a big general question, but I have seen bigger ones on this forum, and I thought I would ask and see what happens. It seems like Chris Stratton, the instrument maker might be able to help, if I am able to follow his explanation with my limited mental faculties.

Thanks again,

Tom Eldredge
