Trying to reproduce Cranal noise from Cinema4d with simplex and Perlin noises Original 'fertility' model courtesy of the AIM@SHAPE Shape Repository

    Hi Laurent:

    I was wondering if you are able to add a noise subroutine to an F(X) evaluate expression
    which would look like the attached pic if it was added to the expression?

    Here is an example Gyroid Gh that might benefit from such a conversion

    Kim, 

    it could be possible but at the moment I just know the components Simplex Noise and Perlin Noise from 4D noise on food4rhino

    http://www.food4rhino.com/project/4dnoise?etx

    these components need coordinate Point(x,y, z), time and a scale. They output values between -1 and 1. So you can use this function. It is what I do.

    For the scale, I put say it is the number of "variations" you want divided by the characteristic size (height, length...) of your object. 

    I also reproduce Dents texture from Cinema4d, instead of multiplying 2 noises you add to sum them. Cranal on Left, Dents on Right
