Create another Perlin curve (or reuse the same one), but double the resolution — so there’s a randomly-chosen line at x = 0, ½, 1, …. Then halve the output value, and add it on top of the first curve.

Aug 13, 2015 · The difference comes from the fact that low-noise filters are more “perfectionistic”, using all the DOFs to explicitly zero the high frequencies (at any cost). Gaussian is more relaxed in that respect. I would say that least squares filters and low-noise are two extreme examples of how noise can be suppressed (non-smooth and smooth).
Jun 22, 2017 · Multiple octaves of Perlin noise. So now we’ve got a useful modification to Perlin noise, but people rarely use plain Perlin noise in their applications. More commonly, people will sum up different frequencies of Perlin noise together to get a fractal-like texture that has detail at multiple different resolution levels.

Perlin noise is ubiquitous in modern CGI. Used for procedural texturing, animation, and enhancing realism, Perlin noise has been called the "salt" of procedural content. Perlin noise is a type of gradient noise, smoothly interpolating across a pseudo-random matrix of values. The noise library includes native-code implementations of Perlin "improved" noise and Perlin simplex noise.
Synthetic textures using Perlin noise are often used in CGI to make computer-generated visual elements – such as object surfaces, fire, smoke, or clouds – appear more natural, by imitating the controlled random appearance of textures in nature. An organic surface generated with Perlin noise.
Step one (Acquire or generate a tile-able Perlin Noise Texture): Acquire or generate a so called "Perlin Noise" texture with a tool of your choice. You can also simply Google image search "Perlin Noise tile-able". Make sure that it is actually tile-able by repeating the texture and make sure there are no visible seems.

The Perlin noise function is defined on a field of real values, where the integer subset of its domain defines the base frequency of the noise. Implementation of the noise function requires coordinates s,t,rto range over multiple integers, though color components only range over [0,1]. Perlin noise is a popular procedural generation algorithm invented by Ken Perlin. It can be used to generate things like textures and terrain procedurally, meaning without them being manually made by an artist or designer. The algorithm can have 1 or more dimensions, which is basically the number of inputs it gets.
