Circle packing math
WebThe topic of 'circle packing' was born of the computer age but takes its inspiration and themes from core areas of classical mathematics. A circle packing is a configuration of circles having a specified pattern of tangencies, as introduced by William Thurston in 1985. This book, first published in ...

In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles. Generalisations can be made to higher dimensions – this is called sph… WebThat is, as you place the larger circles, you quickly get to the point where large circles will no longer fit, but you might be able to fit four-ish times as many circles of half the radii. So if you pack as densely as possible, then a histogram of radii would be highly biased towards the smaller diameters.
