Patterns

Procedural patterns are frequently use in production for add details or matter in elements.

Available patterns are:
  • fBm
  • Noise
  • Oscillation
  • Radial Grad
  • Raindow
  • Shape
  • Turbulence
  • Zoneplate
Here are examples:

fBm
fBm or Fractional Brownian Motion.
2 inputs:
  • XYZ stand as xyz coordinates in the RGB components
  • OLG stand as Octave Lacunarity Gain values in the RGB components

Noise
A Noise is the most simple of noises generators.
1 input:
  • XYZ stand as xyz coordinates in the RGB components

Oscillation
Ocillation is a Sine and Cosine generator.
They are really basic trigonometric functions.



Radial Grad
Radial Gradient generate a circle at a center XY of the size XY.
The gradient start at 1 at the center and decrease until 0 at the size.

2 inputs:
  • CenterXY stand as xy coordinates in the RG components
  • SizeXY stand as XY scale values in the RG components


Rainbow:
Rainbow generate a Hue gradient from X coordinate.

3 inputs:
  • value stand for the luminance of the gradient
  • Saturation stand for the saturation level
  • X is the coordinate of the gradient


Random:
Random generate randomized noise.
This is very rough computation.

1 input:
  • XYZ stand as xyz coordinates in the RGB components


Shape:
This node generate primitive shapes.
Shapes list:
  • Horizontal
  • Vertical
  • Radial
  • Circular
  • Line Horizontal
  • Line Vertical
  • Square


Turbulence:
This is one of the most soffisticated noise generator.

2 inputs:
  • XYZ stand as xyz coordinates in the RGB components
  • OLG stand as Octave Lacunarity Gain values in the RGB components



Zoneplate:
Zoneplate generate concentric circles.

3 inputs:
  • CenterXY stand as xy coordinates in the RG components
  • Variance stand as scale value in the R components
  • Offset stand as cyclable value in the R components
