[SOLVED] Perlin noise - smooth interpolation issues
I don't like the result of the smooth interpolation: the linear interpolation gives straight lines and the cosine interpolation gives funny squares.
Anyone came up with whatever else solution that brings a better result on the generated perlin? As I understand it, it should simply be a parabolic LERP, no?

I’ve always used the following polynomial for interpolation (the same presented in the paper “Improving noise” by Perlin): 6t5 - 15t4 + 10t3
Thanks to you, I discovered that I have been living under a rock for couple of years as I had never heard of improved noise before! Thanks for pointing this out.
