WebAn improvement by Perlin to his original non-simplex noise Simplex Noise, is the replacement of the cubic Hermite curve ( f(x) = 3x^2-2x^3, which is identical to the smoothstep() function) with a quintic interpolation curve ( f(x) = 6x^5-15x^4+10x^3).

WebOct 29, 2024 · Worley noise is a noise function introduced by Steven Worley in 1996. In computer graphics it is used to create procedural textures, [1] i.e. textures that are created automatically with arbitrary precision and do not have to be drawn by hand. Worley noise comes close to simulating textures of stone, water, or biological cells.

"WebPerlin Noise is the award winning type of gradient noise developed by Ken Perlin in 1982. Simplex Noise developed by Ken Perlin in 2001 has similar results to Perlin Noise with less computational requirements than Perlin. The idea of Simplex is to divide the N dimensional space into triangles that reduces the number of data points. " - Perlin-worley noise
