Hi, I am working with Voronoi. However, I need to draw offset polygon. In my case, it will be negative offset polygon (the inner polygon will shrink). Can any one help me out. I tried, but did not get it. I am trying to provide the the coordinates of the original polygon and amount of offset (it may be positive for expansion and negative value for contraction). My case, the polygon is arbitrary shaped, i.e. it can be of any number of sides but of course convex polygon. I will appreciate if someone can help me out.
Thanks, Tanvir

Hi,
Did you find your answer? I'll be interested in offseting some polygons as well.
Thanks, Razvan

for ii = [0 1 3]
xoff = ii;
yoff = 1;
t = 0.05:0.01:2*pi;
x1 = avgdistbig*cos(t)+xoff;
y1 = avgdistbig*sin(t)+yoff;
pgon = polyshape(x1,y1);
hold on;plot(pgon)
end
