Turbulize Color by Gradient

 
 
 

Turbulizes a color or a channel using the gradient value.

Category: Color

Output Ports: out

Pos

Controls the position of markers on the gradient:

  • Color Markers — If a color marker is selected, the Pos value indicates its position, on a scale of 0.00-1.00, within the entire gradient.
  • Interpolation Markers — If an interpolation marker is selected, the Pos value indicates its position, on a scale of 0.00-1.00, between its associated pair of color markers.

Cubic

Switches between linear and cubic interpolation of the gradient. Cubic interpolation results in a smoother transition between gradient colors, while linear interpolation results in sharper transitions.

Turbulence Scale

The granularity of the noise pattern. The smaller the turbulence scale, the finer the noise.

Animated

Turn on to generate a new set of random numbers at each frame. Otherwise, the same numbers are always returned when the current time changes.

Animated Speed

Defines the speed at which the noise evolves over time. This only has an effect when the time-varying option is on.

Seed

Defines the sequence of random numbers used. If you require that two nodes generate different sets of values with the same parameters, then assign them different seeds.

Complexity

Defines the number of octaves to be added to the turbulence. The value of the turbulence is calculated such that for each octave a noise of half the amplitude and twice the frequency is added. A complexity of one is simple noise with no fractal pattern.

Complexity has an impact on performance. A turbulence with 2 octaves takes twice as long to calculate than a turbulence with only 1 octave.
