Is it the “Perlin noise” ?

and the “Perlin noise” is the “improved perlin noise” ?

Anyone knows the c code of the “Original Perlin noise”?

Yes I believe that is what it is.

If you want an example of how to write your own perlin noise function have a look at the Texturing & Modeling: A Procedural Approach book. In one chapter it gives you some example c code along with a lattice table of points to get you going.

If you were to have reverse engineered Pixar's perlin noise, better be careful where you use that.

seems a warning……?? :shock:

Since Pixar provides usable C++ code examples in their docs it may be best to ask their support what implications there are to using it.

I would guess it's ok to use on your licensed machine or network, but not beyond that.

that's fine
