Re: [CAD_CAM_EDM_DRO] digitized point smoothing algorithm

Hi Alan,

I am hoping to find an algorithm that I can code into my existing digitizing
program. I do not want to have to exit and go through several steps.

Last night I went up to my favorite Proffessor friend's office at UMR, and
we did some experimenting on paper with a smoothing algorithm which produces
new vertexes and edgepoints, which I had found from UCLA. It seems like it
will work, and I am going to try it out in the next day or so.

If others are interested, I will pass along what I find if it works out.

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.

Chris Stratton, the instrument maker might be able to help, if I am able to
