Voronoi
In: Texture Generators /Noises
Intermediate
Description
The Voronoi node generates a 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).

| 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 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 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 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 Voronoi noise. -
Distortion Scale Multiplier Float
Controls the scale of the deforming pattern used in the warping effect controlled by the Distortion Intensity. -
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.
-
Style IntegerSets the method rendering the data of the 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 FloatAdjusts the thickness of the edges detected between cells of the 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. -
Non Square Expansion Boolean
Enables compensation of squash and stretch with non-square ratios.
