❔ 3D Arrays = good tutorial?

Does someone have a good guide/tutorial how to explain 3d arrays. the course on udemy isnt to clear for me .
what of the 3 axes is wich? ( z, x , y)
How does it move , etc.

3D arrays? you mean int[,,]int[,,], yes?

Jens IOP•8/31/23, 5:49 PM

yes multi dimensional arrays . [,,] is correct

ero•8/31/23, 5:50 PM

then it's your choice what goes where

Jens IOP•8/31/23, 5:51 PM

wdym?

ero•8/31/23, 5:51 PM

well, you're the one populating it

ero•8/31/23, 5:51 PM

it's just an array

ero•8/31/23, 5:51 PM

you can put anything you want in it

ero•8/31/23, 5:52 PM

int[,,] foo =
{
  {
    { 1, 2, 3 },
    { 4, 5, 6 }
  },
  {
    { 7, 8, 9 },
    { 0, int.MaxValue, int.MinValue }
  }
};

int[,,] foo =
{
  {
    { 1, 2, 3 },
    { 4, 5, 6 }
  },
  {
    { 7, 8, 9 },
    { 0, int.MaxValue, int.MinValue }
  }
};

this could be x, y, zx, y, z, y, z, xy, z, x, foo, bar, bazfoo, bar, baz, p, _9999, Γp, _9999, Γ

Jens IOP•8/31/23, 5:56 PM

yeah but i mean, whats the index of those numbers

ero•8/31/23, 5:57 PM

foo[0, 0, 0]foo[0, 0, 0]

ero•8/31/23, 5:58 PM

i see where you might be confused. the

here would be at foo[1, 1, 0]foo[1, 1, 0]

Jens IOP•8/31/23, 5:58 PM

and how do they increase ?

ero•8/31/23, 5:58 PM

well the first index is the outermost array. the second is the next layer, and the last is the final array

ero•8/31/23, 5:59 PM

it's an array of arrays of arrays

Jens IOP•8/31/23, 5:59 PM

yeah [,] = like 00 0102
10 11 12

Jens IOP•8/31/23, 6:00 PM

so if you added one more { }

Jens IOP•8/31/23, 6:01 PM

then it would be 1 0 0

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
