[comp.graphics] Polygon approximation

tubbsk@ure.CS.ORST.EDU (Ken Tubbs) (08/02/90)

I am looking for information/algorithms/code for polygon approximation.
Specifically, given a list of points which represent a 2D region I would
like to find a polygonal approximation to this region using a minimum
number of vertices.  Has any one done this and would you be willing to
share your code?  I have implemented the alogrithm in "Algorithms for
Graphics and Image Processing" by Pavlidis but I don't find its
performance to be very good.  (Or I've got bugs!)

Thanks in advance,
