# 3.8.2: Closest Points

Assume you have two sets of points: say **“P”** and **“C”**. Further imagine you want to have a network that connects each point of the first set with a predefined number of its nearest neighbors in the second set (input **“N”**) or to points in set two that lie within a given distance **“LDist”**. In that case the “Nearest Neighbor”-component will be the right choice (see fig. 3.8.2.1). It outputs at **“P”** a data tree with branches containing the points of set **“C”** which are closest to the **“P”**-points. The order of branches corresponds to the points in **“P”**. The output **“i”** returns the indexes of the nodes in **“C”**, and **“D”** the distances.
