Perlin Noise 1D

This means that this modifier will give an identical result for two strokes with the same length and sampling interval.

Frequency

How dense the noise is (kind of a scale factor along the stroke).

How much the noise distorts the stroke in the Angle direction.

Seed

The seed of the random generator (the same seed over a stroke will always give the same result).

The “level of detail” of the noise.

Angle

In which direction the noise is applied (0.0 is fully horizontal).
