将1d数组索引转换为3d数组索引? [英] Convert a 1d array index to a 3d array index?

问题描述

我有一个要转换为3d数组索引的3个整数的整数，这是我正在研究的示例.

I've got a int that I want to convert to 3 ints for the index of a 3d array, here's an example of what I'm on about.

byte[,,] array = new byte[XSize, YSize, ZSize];

int i = 0;

//other code

array[#,#,#] = cur;

//other code

我不知道如何仅从i中获取#，#，#的正确数字.

I don't know how to get the correct numbers for the #,#,# from just i.

推荐答案

假设您要依次遍历Z，Y和X.

Supposing you want to iterate through Z, then Y, and then X. . .

int zDirection = i % zLength;
int yDirection = (i / zLength) % yLength;
int xDirection = i / (yLength * zLength);
