Simplex Noise Rust Implementation (2D, 3D)\n========================================================\n\n## About Perlin's \"Simplex\" Noise\n\n- Perlin's \"Classic\" Noise (1984) is an algorithm producing pseudo-random fluctuations\n  simulating natural looking variations, producing paterns all of the same size.\n  It is a kind of gradiant-noise algorithm, invented by Ken Perlin while working\n  on visual special effects for the Tron movie (1982).\n  It works by interpolating pseudo-random gradiants defined in a multi-dimensionnal grid.\n  [Ken Perlin original references](http://mrl.nyu.edu/~perlin/doc/oscar.html)\n- Perlin's \"Improved\" Noise (2002) switches to a new interpolation fonction with\n  a 2nd derivative zero at t=0 and t=1 to remove artifacts on integer values,\n  and switches to using predefined gradients of unit lenght to the middle of each edges.\n  [Ken Perlin original references](http://mrl.nyu.edu/~perlin/paper445.pdf)\n- Perlin's \"Simplex\" Noise (2001) rather than placing each input point into a cubic grid,\n  based on the integer parts of its (x,y,z) coordinate values, placed them onto a simplicial grid\n  (think triangles instead of squares, pyramids instead of cubes...)\n  [Ken Perlin original references](http://www.csee.umbc.edu/~olano/s2002c36/ch02.pdf)\n\n## Coherent noise\n\nA coherent noise is a type of smooth pseudorandom noise with following properties:.\n- same input will always return the same output.\n- small change of the input will produce small change of the output.\n- large change of the input will produce random change of the output.\n\n## Code attribution\n\nThis Rust implementation is based on the speed-improved Java version 2012-03-09\nby Stefan Gustavson (original Java source code in the public domain).\nhttp://webstaff.itn.liu.se/~stegu/simplexnoise/SimplexNoise.java:\n- Based on example code by Stefan Gustavson (stegu@itn.liu.se).\n- Optimisations by Peter Eastman
