Randomness: 0.5.
Randomness: 0.25.
Randomness: 0.0.
属性
- 规格尺寸
用于计算噪波的空间维度。
- 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.
- 特性
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.

- 平滑 F1
A smooth version of F1.

- 到边缘的距离
The distance to the edges of the Voronoi cells.
距离。
Distance smaller than 0.05.
- N 球体半径
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.
The n-sphere radius can be used to create tightly packed n-spheres.

- 间隔矩阵
The distance metric used to compute the texture.
- 欧几里德
Use the Euclidean distance metric.
- 曼哈顿点距
Use the Manhattan distance metric.
- 切比雪夫
Use the Chebychev distance metric.
- 闵可夫斯基
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.
闵可夫斯基指数: 0.5(闵可夫斯基 1/2)。
闵可夫斯基指数: 1.0(曼哈顿)。
闵可夫斯基指数: 2.0(欧几里得)。
闵可夫斯基指数: 32.0(切比雪夫近似)。
输出
- 距离
距离。
- 颜色
单元格颜色。颜色是任意的。
- 位置
特征点的位置。
- W
特征点的位置。
- 半径
N维球面半径。
注意
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.
示例
The difference between F1 and Smooth F1 can be used to create beveled Voronoi cells.
