This is a clean, fast, modern and free Perlin Simplex noise function.
If we change float to double it could be even faster but there is no double type in Blueprint
All Public Functions are BlueprintCallable so they can be used in every blueprint
Scaled Version SimplexNoise 1D,2D,3D & 4D
InRange version SimplexNoise 1D,2D,3D & 4D
SimplexNoise Function retruns float value between 0 - 1
SimplexNoise Scaled retruns float value between 0 - scale factor
SimplexNoise In Range returns float value between minRange - maxRange
inFactor value added to all functions to set frequency of the noise[ Recomended values form: 0.1 - 0.00001 ]
GetSimpleNoise1D_EX (float x, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise2D_EX (float x, float y, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise3D_EX (float x, float y, float z, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise4D_EX (float x, float y, float z, float w, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne) Version: 1.0 (5.1) Home Page: https://github.com/devdad/SimplexNoise
