A friend who does digital FXs for Hollywood told me that they distinguish between two types of Perlin noise: the classical algorithm that Perlin came up with in the 1980s and the newer simplex noise that he came up with in 2001. The simplex noise is more often used now because it is less computationally intensive and has fewer artifacts.
My question is: Is the noise() function in processing the classic Perlin noise or the simplex Perlin noise?
