Perlin Noise
A smooth gradient-noise function that creates natural-looking randomness for clouds, marble, fire and terrain. Ken Perlin developed it in the early 1980s while working on Tron, to escape the machine-made look of early CGI, and published it in 1985.

- 01Cloud-like organic blobs
- 02Smooth marbled veining
- 03No visible repetition
Why it happens
Random gradient vectors on a lattice are interpolated with a smooth curve, and summing several scales of this noise gives rich, continuous, natural-looking variation.

Image edit prompt“Overlay this image with Perlin-noise textures: let smooth, cloud-like turbulence distort surfaces into marbled veins, billowing organic gradients and flowing contour bands in a restrained palette of grays and warm tones, with no repeating patterns or hard seams. Keep the original subject and composition.”
