feTurbulence {gridSVG} | R Documentation |
This filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble.
feTurbulence(baseFrequency = 0, numOctaves = 1, seed = 1, stitchTiles = FALSE, type = c("turbulence", "fractalNoise"), ...)
baseFrequency |
The base frequency (frequencies) parameter(s) for the noise function. If a two element numeric vector is provided, the first number represents a base frequency in the X direction and the second value represents a base frequency in the Y direction. If one number is provided, then that value is used for both X and Y. |
numOctaves |
The |
seed |
The starting number for the pseudo random number generator. |
stitchTiles |
If If |
type |
Indicates whether the filter primitive should perform a noise or turbulence function. |
