1. Definition

A multijittering sampler takes a parameter \(N\). It subdivides the given rectangle in \(N \times N\) subrectangles. Each of these subrectangles is then subdivided once more into \(N \times N\) subsubrectangles. In each of the \(N \times N\) subrectangles, a different subsubrectangle is chosen. For example, the lower-left subsubrectangle is selected in exactly one subrectangle.

Shuffling this around gives:
