C4DNoise.InitFbm(self, lMaxOctaves, rLacunarity, h)¶ Initializes fractal brownian motion.
- Parameters
lMaxOctaves (int) – The maximum octave.
rLacunarity (float) – This parameter controls the scale of each successive fractal overlay.
h (float) – H-Parameter
- Return type
bool
- Returns
Initializes fractal brownian motion

C4DNoise.Noise(self, t, two_d, p, time=0.0, octaves=4.0, absolute=False, sampleRad=0.25, detailAtt=0.25, t_repeat=0)¶ Samples a 2D or 3D noise.
- Parameters
t (int) –
The noise Type: Noise Types
Note
Please use
InitFbm()before you use one of the following noise types: NOISE_ZADA, NOISE_DISPL_VORONOI, NOISE_OBER, NOISE_FBM, NOISE_BUYA.two_d (bool) – True for 2D Sampling, False for 3D Sampling
p (c4d.Vector) – Noise coordinate.
time (float) – Time.
octaves (float) – Octaves, if supported. See
HasOctaves()absolute (bool) – Absolute value, if supported. See
HasAbsolute()sampleRad (float) – Sample radius.
detailAtt (float) – Detail attenuation.
t_repeat (int) – Must be 2^x - 1, where x = [1..10], i.e. one of 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1023. A noise repeats itself in time every 1024 units. Using a smaller repeat the noise will repeat at an earlier time.
- Return type
float
- Returns
Noise sample.
-
C4DNoise.SNoise(self, p, lRepeat, t=0.0)¶ Generate a periodic signed noise value.
- Parameters
p (c4d.Vector) – Noise coordinate.

float

Signed noise value, this is between -1.0 and 1.0.

t (float) – The time.
- Return type
float
- Returns
Noise sample.
