description:"<p>Returns the Perlin noise value at specified coordinates. Perlin noise is\na random sequence generator producing a more natural ordered, harmonic\nsuccession of numbers compared to the standard <b>random()</b> function.\nIt was invented by Ken Perlin in the 1980s and been used since in\ngraphical applications to produce procedural textures, natural motion,\nshapes, terrains etc.<br /><br /> The main difference to the\n<b>random()</b> function is that Perlin noise is defined in an infinite\nn-dimensional space where each pair of coordinates corresponds to a\nfixed semi-random value (fixed only for the lifespan of the program; see\nthe noiseSeed() function). p5.js can compute 1D, 2D and 3D noise,\ndepending on the number of coordinates given. The resulting value will\nalways be between 0.0 and 1.0. The noise value can be animated by moving\nthrough the noise space as demonstrated in the example above. The 2nd\nand 3rd dimension can also be interpreted as time.<br /><br />The actual\nnoise is structured similar to an audio signal, in respect to the\nfunction's use of frequencies. Similar to the concept of harmonics in\nphysics, perlin noise is computed over several octaves which are added\ntogether for the final result. <br /><br />Another way to adjust the\ncharacter of the resulting sequence is the scale of the input\ncoordinates. As the function works within an infinite space the value of\nthe coordinates doesn't matter as such, only the distance between\nsuccessive coordinates does (eg. when using <b>noise()</b> within a\nloop). As a general rule the smaller the difference between coordinates,\nthe smoother the resulting noise sequence will be.
