Simplex noise is easy to implement in hardwareįor a detailed explanation about simplex noise, here is a nice PDF: Simplex noise demystified.Simplex noise has a well-defined and continuous gradient everywhere that can be computed quite cheaply.Simplex noise has no noticeable directional artifacts.Simplex noise scales to higher dimensions (4D, 5D and up) with much less computational cost, the complexity is for dimensions instead of the of classic noise.simplex noise has a lower computational complexity and requires fewer multiplications.Compared to Perlin noise, simplex noise has the following advantages: Simplex noise is an improved version of Perlin noise.
