Given a cube $C$ with side length $N\cdot d$.
Q:
Is there a method to fulfill the $C$ with balls of diameter $d$.
How to find the centers of these balls by a given coordinate.

Assuming you are happy with cubic packing, the centers of the balls would be at the exact same locations as the centers of the N^3 small cubes, with side length d, that could be packed into C.
