Perlin Noise 2D
The Perlin Noise 2D modifier adds one-dimensional Perlin noise to the stroke. The modifier generates noisy displacements using 2D coordinates of stroke vertices as the input of the noise generator.
- Frequency (頻度)
How dense the noise is (kind of a scale factor along the stroke).
How much the noise distorts the stroke in the Angle direction.
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.
In which direction the noise is applied (0.0 is fully horizontal).
