NOISE_GRAD3D

THE BOX'S MAIN HELP:

This function generates three-dimensional noise.
PP is the vector seed for the noise function.
GG is the vector for the gradient of the computed texture at PP.
The return value will be a scalar which lies in the range [0,1].

PP (input):

This must be a vector. 
This is the seed for the noise function.
The default is the surface intersection point.

GG (output):

This vector is assigned the gradient of the computed texture at PP.

OUT (output):

This function generates three-dimensional noise.
PP is the vector seed for the noise function.
GG is the vector for the gradient of the computed texture at PP.
The return value will be a scalar which lies in the range [0,1].
