Voronoi Fractal
In: Texture Generators /Noises
Intermediate
Description
The Voronoi Fractal node generates a fractal 3D Voronoi noise mapped to a 2D image using a Z-down orthographic projection.
This node can be tested with Cube GBuffers as input instead of an actual baked map (as seen in the Example Image below).
Alert:
This noise is meant to be used with the GPU engine only (i.e., Director OpenGL). Go to Tools > Switch engine... or press the F9 key to select the desired engine.
Parameters
- Invert Boolean
Inverts the output image. - Scale Float
Controls the scale of the fractal Voronoi noise.
Note: When Tiling is enabled on any axis, the scale adjustement is stepped. This is expected. - Size Float3
Controls the size of the fractal Voronoi noise in the X, Y and Z axes. Non-uniform values result in a stretching or squashing effect.
Note: When Tiling is enabled on any axis, the size adjustment is stepped. This is expected. - Offset Float3
Applies an offset to the position of the fractal Voronoi noise in the X, Y and Z axes. - Disorder Float3
The intensity of the random offset applied to each point of the noise in the X, Y and Z axes. - Distortion Intensity Float
Controls the intensity of a warping effect applied on the fractal Voronoi noise. - Distortion Scale Multiplier Float
Controls the scale of the deforming pattern used in the warping effect controlled by the Distortion Intensity. - Min Level Integer
The minimum level of of repetition used in the fractal pattern. A wider minimum/maximum range results in a richer pattern with variation on more frequency ranges. - Max Level Integer
The maximum level of of repetition used in the fractal pattern. A wider minimum/maximum range results in a richer pattern with variation on more frequency ranges. - Roughness Float
Controls the balance between low and high levels of repetition in the fractal pattern.
Note: A value of 0 results in an output which is not in line with other low values following it. This is expected.
Note 2: This parameter is only available when the Blend Mode parameter is set to Add. - Lacunarity Float
Controls how the applied fractal pattern fills space. A higher value results in less gaps in the pattern and a denser noise. - Global Opacity Float
Controls the range of the fractal Perlin noise values from 0. - Rounded Curve Float
Rounds the slope around each point of the noise to make it convex.
Note: This parameter is not available when the Style parameter is set to Edge. - Distance Scale Float
Adjusts the distance of the gradient around each point of the noise. - Distance Mode Integer
Sets the method to compute the distance gradient around each point of the noise:
- Euclidean
- Manhattan
- Chebyshev
- Minkowski - Minkowski Number Float
The order p of the Minkowski distance. If we divide the distance gradient into quadrants, this number impacts these quadrants as follows:
- p is exactly 1: Straight
- p is lower than 1: Concave
- p is greater than 1: Convex
Interesting values:
- 1.0: Manhattan distance
- 2.0: Euclidean distance
- Infinity: Chebyshev distance
Note: This parameter is only available when the Distance Mode parameter is set to Minkowski. - Blend Mode Integer
Sets the method of blending together the values of overlapping cells in space:
- Add: Add the values
- Max: Retain the highest value
- Min: Retain the lowest value - Style Integer
Sets the method rendering the data of the fractal Voronoi noise, considering the noise is based on a set of points in space:
- F1: the distance to the closest point in space
- F2: the distance to the second closest point in space
- F2-F1
- F1*F2
- F1/F2
- Edge: the edge between each cell of the noise in space
- Random color: assign a random flat color to each cell of the noise in space - Edge Thickness Float
Adjusts the thickness of the edges detected between cells of the fractal Voronoi noise. Edges are detected in the X, Y and Z axes, thus some thicknesses may increase quicker than other depending on the cells' depth.
Note: This parameter is only available when the Style parameter is set to Edge. - Random Color Seed Mode Integer
Sets the method of acquiring the random seed for the color selection per cell:
- Global Random Seed: Use the seed inherited by the node
- Manual Seed: Use a discrete seed
Note: This parameter is only available when the Style parameter is set to Random color. - Random Color Seed Integer
The discrete random seed which should be used for the color selection per cell.
Note: This parameter is only available when the Style parameter is set to Random color and the Random Color Seed Mode parameter is set to Manual Seed. - Enable Tiling Boolean
Adjusts the fractal Voronoi noise so its resulting pattern repeats in the X, Y and Z axes.
