QMC simply focuses on orthogonal well-distribution which by itself can grant some degree of "diagonal" well-distribution, some (but not the simplest) methods further avoid diagonal clumping by more coherent means. Consider e.g. random points each in a different grid's cell: 2 neighbors might still risk vicinity, as a set there's uniform distribution and good avoidance. | |
