# 3.8.3: 多维最近点 (Closest Points Multi-dimensional)

![图3.8.3.1：在5-D设置中连接到其最近点的单位体积中的随机点](/files/-M9XuVmwnJETcoJBKrmj)

最近点的搜索可以被概况为任意数量的维度。如果超过三个，则使用**“Closest Point Multi-Dimensional（最近多维点）”**运算器。图3.8.3.1显示了一个五个维度的范例：第一至第三维度表示空间。第四维度是每个点与粗红色基准线之间的最短距离。基准线在与其最短距离的线相交点处的曲线参数为五个维度。每个随机生成的点都与其最近的点相连接。从图3.8.3.1可以看出，所得的线段以某种方式与基准曲线对齐。

组件上有三个输入端口：

| **"P"** | 需要一个数据树，其中每个分支包含n个值，这些值是点的坐标。 **“P”**输入可以定义与最近点连接可以开始的点。                                                                   |
| **"C"** | 与**“P”**相同类型的输入。它包含与最近点连接可以终止的点。                                                                                    |
| **"N"** | 在**“P”**中每个点可以生成的最近点连接数量。**“Multi-dimensional Nearest Neighbors （多维最近点）”**运算器的输出**“i”**是连接性图解。 |
