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
How dense the noise is (kind of a scale factor along the stroke).
- Amplitude
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).
- Octaves
The "level of detail" of the noise.
- 角度
In which direction the noise is applied (0.0 is fully horizontal).
