WOODGRAIN
THE BOX'S MAIN HELP:
This function returned a woodgrain pattern. PP is the seed to the turbulence function. A is the first point of the axis for the rings. B is the second point of the axis for the rings. NUM controls the number of rings. FQ controls the frequency of the turbulence in the rings. OCT controls the amount of turbulence in the rings. SWL controls the amount of swirl in the rings.
PP (input):
This must be a varying point. The default is the surface point, P. This is the seed to the turbulence function.
A (input):
This must be a point. The default is the origin. This is the first point of the axis for the rings.
B (input):
This must be a point. The default is the z_axis. This is the second point of the axis for the rings.
NUM (input):
This must be a float. The default is 4.0. This controls the number of the rings.
FQ (input):
This must be a float. The default is 1.0. This controls the frequency of the turbulence in the rings.
OCT (input):
This must be a float. The default is 4.0. This controls the amount of turbulence in the rings.
SWL (input):
This must be a float. The default is 0.3. This controls the amount of swirl in the rings.
OUT (output):
This function returned a woodgrain pattern.
