I would like to know why Perlin noise is still so popular today after Simplex came out. Simplex noise was made by Ken Perlin himself and it was suppose to take over his old algo
I wouldn't be at all surprised if it was simply because of the name. You have to choose between Perlin noise and Simplex noise. The latter is newer and has some advantages. But, you know, it sounds like the 'simple' version of the two. I'll go with the complexer one; noise is supposed to be complex, isn't it?
People tend to be rather irrational.
