Houdini Vex – Neighbours_Nearpoints _ S1EP6
S1EP6 – Neighbours/Nearpoints
Welcome to S1EP6 of this Houdini Vex Series.
Neighbours and Nearpoints are two seperate functions, that return arrays of points. The main difference between both is, that Neighbour will return a pointnumber of the closest connected point of the input point. Connected in this case by an edge. Nearpoint will return a pointnumber of the closest point in space. So Connectivity (based on connected points) and Proximity (based on nearess in space).

S1EP6 – 邻居/近点
欢迎来到这个 Houdini Vex 系列的 S1EP6。
Neighbors 和 Nearpoints 是两个独立的函数，它们返回点数组。两者之间的主要区别在于，Neighbor 将返回输入点的最近连接点的点号。在这种情况下通过边连接。 Nearpoint 将返回空间中最近点的点号。所以连通性（基于连接点）和邻近性（基于空间的接近程度）。
