Re: digitized point smoothing algorithm

Decide your accuracy tolerance, then using an equation for the end
points of lines or arcs, (G01 and G03 etc in G code) compare the
equation to each of your points.

As long as the points are within the tolerances, throw out the points
and use the equation.

Decide your radius tolerance, if the deviation from the linear
equation is greater than the radius, change to arc. If it is less,
change to linear.

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.

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.
