Inner offset Polygons

[Bradford Cox]

 Hello all, I am trying to solve a problem which is the calculation of an inner offset polygon based on a set of original points and a given offset distance. It is acceptable for the inner polygon to not be a "mirror" image of the original polygon since certain sides will converge to zero length, etc. Currently my focus has been in the area of straight skeletons. I intend on first creating a straight skeleton and then somehow generating the sides of the new inner polygon based on the the skeleton lines. (I am not sure how to do this just yet!) Does anyone have any suggestions for either the straight skeleton approach or some other approach? Thanks, Bradford Cox
