Attribute Statistic Node

The Attribute Statistic node evaluates a field on a geometry and outputs a statistic about the entire data set.

输入

几何数据(Geometry): Standard geometry input.
选择: A boolean field input for each element indicating whether to include its value in the statistics result If the boolean is false, the corresponding value from the Attribute input will be ignored.
属性: The attribute field to query a statistic from.

数据类型

浮动: The output will be a single floating-point value.
矢量: The output will be a vector of three floating-point values. All calculations are elementwise.

域

The attribute domain used for the statistics and to evaluate the input Attribute field on.

平均值: The average value of all data.
质心: The median value of all data.
Sum: The sum value of all data.
最小值: The min value of all data.
最大值: The max value of all data.
范围: The difference between the max and min value.
标准差: How much values differ from the mean. A low standard deviation indicates that the values are grouped tightly together at the mean. A high standard deviation indicates that the values are spread out over a large range.
Variance: The variance of all data, defined as the square of the standard deviation.
