How does this algorithm relate to "blue noise" from a few slides ago? Is "blue noise" actually a rigorous algorithm or just a family of algorithms?

Blue noise refers to a specific relationship between frequency and amplitude in the spectrum (FFT); it is a property of the sampling itself, rather than any algorithm used to generate it.

Poisson disk sampling and Lloyd relaxation are two simple techniques used to (try to) get a blue noise sampling.
