The noise function takes three double values and outputs a value. Case 1: Improved Noise reference implementation First, there is the Improved Noise reference implementation from Ken Perlin himself. There are several implementations and example code that (try to) implement Perlin noise. Please upvote when I'm correct, comment when not :) Since no one is going to write up an answer from the comments, I'm trying myself. If the solution would be to have a custom noise function, I would be interested if it could be implemented using Boost.Random (or C++11's Standard C++ Library classes).Įdit: To answer what I mean with 'best' way: What's the best way that gives me Perlin noise like it was supposed to work, e.g. Given the same seed value, the same noise values should be generated. So my question would be, what the best way would be to add a seed value to Perlin noise generation is.

Other articles suggest using other noise functions. Another one uses a 3D seed function and uses the fixed seed value as the z value (couldn't find the example just now). However I found example code where one added the seed value to the function parameters calculating the noise value for each octave (see PerlinNoise::Total() in the linked code). Other implementations take a seed value to get different noise depending on the noise value. I'm trying to implement 2D Perlin noise generation in C++, and some implementations I found use no seed at all ( here, here or here).
