  POV-Ray 3.6 Documentation Online View Waveforms Turbulence Noise Generators

There are three noise generators implemented. Changing the noise_generator will change the appearance of noise based patterns, like bozo and granite.

  • noise_generator 1 the noise that was used in POV_Ray 3.1
  • noise_generator 2 'range corrected' version of the old noise, it does not show the plateaus seen with noise_generator 1
  • noise_generator 3 generates Perlin noise

The default is noise_generator 2

Note: The noise_generator can also be set in global_settings Waveforms Turbulence
