Packing circles in the hyperbolic plane, Java … WebIf the circle packing is on the plane, or, equivalently, on the sphere, then its intersection graph is called a coin graph; more generally, intersection graphs of interior-disjoint geometric objects are called tangency graphs or contact graphs. Coin graphs are always connected, simple, and planar.

WebApplications. Hexagonal tiling is the densest way to arrange circles in two dimensions. The honeycomb conjecture states that hexagonal tiling is the best way to divide a surface into regions of equal area with the least total perimeter. The optimal three-dimensional structure for making honeycomb (or rather, soap bubbles) was investigated by Lord Kelvin, who … WebThe principles of packing circles into squares can be extended into three dimensions to cover the concept of packing spherical balls into cubic boxes. As with 2D, the optimal … WebIt belongs to a class of optimization problems in mathematics, which are called packing problems and involve attempting to pack objects together into containers.
