3d-adjacency 中文文档教程
3d-adjacency
从 3d 数组中查找相邻单元格的“集群”。 该阵列不需要必须是立方体，但它确实需要是直角棱柱。
example
假设你有一个三维数组，里面全是 0 和 1。 0 是白色，1 是绿色。 ，它可能看起来像：
从图形上看
你想要的是一组相连的绿色单元格。 它可能看起来像：

， 这正是这个模块提供的！ 雅虎！

[1, 0, 1], [0, 0, 0], [1, 0, 2],

const groups = adj3d.find(exampleCube)

“嘿，为什么输出与输入不匹配相同的形式？”
有效的问题。 具体来说，输出是一组坐标+值的对象。 输入是实际数据。 尽管人们可能希望输出类似于 [ [0, 1, 2] ]，其中 0, 1, 2 是坐标，但输入不是坐标集首先。

3d-adjacency
find "clusters" of adjacent cells from a 3d array. the array does not need to be cubic, but it does need to be a rectangular prism.
example
suppose you had a three dimensional array, full of 0s and 1s. 0s are white, and 1s are green. graphically, it may look like:
what you desire is the sets of connected green cells. graphically, it may look like:
well, that's exactly what this module provides! yahoo!

"Hey, why is output not matching the same form as the input?"
Valid question. Specifically, the output is a set of objects that are coordinates+values. the input is the actual data. Although one might expect the output to be something like [ [0, 1, 2] ], where 0, 1, 2 are coordinates, the input was not coordinate sets to begin with.
