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?

[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.

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.

Took me a while but I got it working as I wanted. I found some old VB6 source code and managed it.

And screenie to show that it does work:
