Sphere Packing Pb 3d Fractal

This model has been generated with Knowledge Patterns. The principle is fractal : you begin with 8 well defined spheres and apply inversions of those spheres by 9 well defined inversion spheres. Then you apply those inversions on resulting spheres, etc. This model have been generated with 4 iterations of this principle

This algorithm is a solution to the sphere packing mathematical pb : how to fill a sphere by an infinite number of spheres that do not intersect with eachothers.
