Results to produce a single output value in range. Lattice points, dots them with the input vector, and interpolates the Looks up the pseudorandom gradients at the nearest Public double Noise(double x, double y, double z) The table simplyĬontains all numbers in in random order. Into a single random index using a lookup in this table. The gradient table is indexed with an XYZ triplet, which is first turned * Borrowed from Darwyn Peachey (see references above). Private readonly double _gradients = new double Private const int GradientSizeTable = 256 X, Y and/or Z coordinates), and then sum them. Means you generate multiple noise values for every pixel (each with different Most of these techniques involve rendering multiple "octaves" of noise. Including terrain generation, cloud rendering, procedural textures, and more. Perlin noise can be used as a starting point for all kinds of things, The noise does not tile,Īlthough it could be made to do so with a few small modifications to the Uses the 3rd dimension to create animated noise. * Converted to C# by Mattias Fagerlund, used the following references for my implementation:ĭarwin Peachey's chapter in "Texturing & Modeling: A Procedural Approach"
