Align Mode

When using the phaseAlign or directionAlign parameters the alignMode sets how the phasor alignment is oriented. For example, Cylindrical Z will create rings around the Z axis.

...

Shaping Mode picks which profile we apply to the phasor result. Sine and cosine make smooth periodic waves. Pulse and pulse centered make solid step functions of the input width at the end or of the center of the period, respectively. The Gabor modes represent the Gabor version of the noise with much less contrast in areas of wave interference. Spline mode lets you use a spline to control the shaping.

Rotate

Use this to rotate the phasor noise direction around the surface normal. The direction of the phasor noise is counterintuitive, it defines the direction of the wave motion, which is orthogonal to the top of the wave crest. This control lets you swing the direction around the normal at any angle.

Filter Scale

The filtering in this noise is based on the final frequency and direction of each phasor wave impulse and is computed and applied to each of the fractal and harmonic octaves. We can't skip entering the kernel loop to save computation time, but the filtering helps a lot with convergence. Decrease the filterScale to recover detail at the cost of more iterations.
