Essentially, the data is composed of a number of randomly sized circles on a flat surface. I have to see how much overlap is there and the thickness of overlap: 1. Does anyone know a code (or suggestions on how to write a code) to find the total overlapping areas of a number of randomly sized circles? 2. Of equal importance, I also need to know how many overlap regions overlap once, twice, thrice,... nXs (where n is the total number of circles) and the corresponding areas of overlap once, twice, thrice, nXs. Any help will be much appreciated!
