Index

The <feTurbulence> SVG filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble. The resulting image will fill the entire filter primitive subregion.

Like other filter primitives, it handles color components in the linearRGB {{glossary("color space")}} by default. You can use {{svgattr("color-interpolation-filters")}} to use sRGB instead.
