There is a well-known algorithm that I believe is used for the "buffer" function in some GIS libraries and applications. I have a vivid memory of reading the paper that describes the algorithm and illustrates how it works, but now I am quite embarrassed: I seem to have misplaced the PDF, and I can't remember the name of the algorithm either. The paper was very interesting and I was hoping to read it again.
Can anyone help with a suggestion of what the algorithm is called that I may be (poorly) remembering? I checked the source code for a couple of libraries but didn't see a reference to the algorithm name.
Of course there is probably more than one such algorithm, but I will recognize the one I was thinking of when I see the name and look at the paper again.
