pack circles into a partial annulus

2014-11-20 Thread Robin Becker
I need to pack circles into a partial annulus ie part of a larger circle bounded by two radii and angles of say 18 & 90. The region is described in polar coords as {(r,theta) | r0<=r<=r1 & theta0<=theta<=theta1}. The circles to be packed have three different radii, but all
