The '''[[wp:Perlin noise|Perlin noise]]''' is a kind of [[wp:gradient noise|gradient noise]] invented by [[wp:Ken Perlin|Ken Perlin]] around the end of the twentieth century and still currently heavily used in [[wp:computer graphics|computer graphics]], most notably to procedurally generate textures or heightmaps.
Line 6:
Either by using a dedicated library or by implementing the algorithm, show that the Perlin noise (as defined in 2002 in the Java implementation below) of the point in 3D-space with coordinates 3.14, 42, 7 is 0.13691995878400012.
''Note: this result assumes 64 bit IEEE-754 floating point calculations. If your language uses a different floating point representation, make a note of it and calculate the value accurate to 15 decimal places, or your languages accuracy threshold if it is less. Trailing zeros need not be displayed.''
