I’ve uploaded three new noise types to the GitHub repository. The first is a PolkaDot style noise in both 2D and 3D which generates smooth falloff dots at random sizes, intensities and locations over a uniform grid. ( There’s even a one-line modification which can give square dots instead : ) )
The second is a 2D Stars noise with behavior similar to the PolkaDot noise but which also allows for the possibility that a dot/star be not drawn. This can generate a sparse distribution of dots which look very suitable for a starry sky.
The third is a noise made more for fun. It is called “cubist” noise due to it resembling a cubist painting style. The problem is that it contains sharp discontinuities and also a possible range of +-infinity which must be arbitrarily clamped ( eg +- 1.0->5.0 ), so it is unfit for displacement or distortion but should produce some interesting results when used for texturing.
