Voronoi Texture Node

../../../_images/render_shader-nodes_textures_voronoi_node.png

Voronoi Texture Node.

The Voronoi Texture node evaluates a Worley Noise at the input texture coordinates.

Inputs

The inputs are dynamic, they become available if needed depending on the node properties.

Vector
Texture coordinate to evaluate the noise at; defaults to Generated texture coordinates if the socket is left unconnected.
W
Texture coordinate to evaluate the noise at.
Scale
Scale of the noise.
Smoothness

The smoothness of the noise.

Properties

Dimensions

The dimensions of the space to evaluate the noise in.

1D
Evaluate the noise in 1D space at the input W.
2D
Evaluate the noise in 2D space at the input Vector. The Z component is ignored.
3D
Evaluate the noise in 3D space at the input Vector.
4D
Evaluate the noise in 4D space at the input Vector and the input W as the fourth dimension.

Higher dimensions corresponds to higher render time, so lower dimensions should be used unless higher dimensions are necessary.

Feature

The Voronoi feature that the node will compute and return.

F1

Compute and return the distance to the closest feature point as well as its position and color.

Position.
Distance To Edge

Compute and return the distance to the edges of the Voronoi cells.

../../../_images/render_shader-nodes_textures_voronoi_distance-to-edge.png

Distance.
../../../_images/render_shader-nodes_textures_voronoi_distance-to-edge_less-than.png

Distance < 0.05.
N-Sphere Radius

Compute and return the radius of the n-sphere inscribed in the Voronoi cells. In other words, it is half the distance between the closest feature point and the feature point closest to it.

../../../_images/render_shader-nodes_textures_voronoi_n-sphere-radius.png

The n-sphere radius can be used to create tightly packed n-spheres.
../../../_images/render_shader-nodes_textures_voronoi_n-sphere-radius_nodetree.png

Node tree for the shader to the left.
Distance Metric

The distance metric used to compute the texture.

Euclidean
Use the Euclidean distance metric.
Manhattan
Use the Manhattan distance metric.
Chebychev
Use the Chebychev distance metric.
Minkowski
Use the Minkowski distance metric. The Minkowski distance is a generalization of the aforementioned metrics with an Exponent as a parameter. Minkowski with an exponent of one is equivalent to the Manhattan distance metric. Minkowski with an exponent of two is equivalent to the Euclidean distance metric. Minkowski with an infinite exponent is equivalent to the Chebychev distance metric.

../../../_images/render_shader-nodes_textures_voronoi_minkowski_one.png

Minkowski Exponent: 1.0 (Manhattan).
