Узел «Текстура Вороного»

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

Входы

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

Вектор

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 of the noise.

Свойства

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.

Возможность

The Voronoi feature that the node will compute.

F1

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

F2

The distance to the second closest feature point as well as its position and color.

Distance.

../../../_images/render_shader-nodes_textures_voronoi_f2-color.png

../../../_images/render_shader-nodes_textures_voronoi_smooth-f1-position.png

Position.

Distance to Edge

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 smaller than 0.05.

N-Sphere Radius

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.

Cell color. The color is arbitrary.

Положение

Position of feature point.

W

Position of feature point.

Примечания

In some configurations of the node, especially for low values of Randomness, rendering artifacts may occur. This happens due to the same reasons described in the Notes section in the White Noise Texture page and can be fixed in a similar manner as described there.
