java.lang.Objectsim.field.grid.AbstractGrid3D
sim.field.grid.DenseGrid3D
public class DenseGrid3D
A wrapper for 3D arrays of Objects.
This object expects that the 3D arrays are rectangular. You are encouraged to access the array directly. The object implements all of the Grid3D interface. See Grid3D for rules on how to properly implement toroidal or hexagonal grids.
The width and height of the object are provided to avoid having to say field[x].length, etc.
We very strongly encourage you to examine SparseGrid3D first to see if it's more appropriate to your task. If you need arbitrary numbers of Objects to be able to occupy the same location in the grid, or if you have very few Objects and a very large grid, or if your space is unbounded, you should probably use SparseGrid3D instead.

Then places into the result Bag any Objects which fall on one of these This function may only run in two modes: toroidal or bounded. Unbounded lookup is not permitted, and so
this function is deprecated: instead you should use the other version of this function which has more functionality.
If "bounded",
then the neighbors are restricted to be only those which lie within the box ranging from (0,0) to (width, height),
that is, the width and height of the grid. if "toroidal",
then the environment is assumed to be toroidal, that is, wrap-around, and neighbors are computed in this fashion. Toroidal
locations will not appear multiple times: specifically, if the neighborhood distance is so large that it wraps completely around
the width or height of the box, neighbors will not be counted multiple times. Note that to ensure this, subclasses may need to
resort to expensive duplicate removal, so it's not suggested you use so unreasonably large distances.
The origin -- that is, the (x,y) point at the center of the neighborhood -- is always included in the results.
This function is equivalent to: getNeighborsMaxDistance(x,y,dist,toroidal ? Grid3D.TOROIDAL : Grid3D.BOUNDED, true, result, xPos, yPos);
public Bag getMooreNeighbors(int x, int y, int z, int dist, int mode, boolean includeOrigin, Bag result, IntBag xPos, IntBag yPos, IntBag zPos)

then the neighbors are restricted to be only those which lie within the box ranging from (0,0) to (width, height),
that is, the width and height of the grid. If "unbounded", then the neighbors are not so restricted. Note that unbounded
neighborhood lookup only makes sense if your grid allows locations to actually be outside this box. For example,
SparseGrid3D permits this but ObjectGrid3D and DoubleGrid3D and IntGrid3D and DenseGrid3D do not. Finally if "toroidal",

You can also opt to include the origin -- that is, the (x,y) point at the center of the neighborhood -- in the neighborhood results.
public Bag getMooreNeighborsAndLocations(int x, int y, int z, int dist, int mode, boolean includeOrigin, Bag result, IntBag xPos, IntBag yPos, IntBag zPos)
For each Object which falls within this distance, adds the X position, Y position, and Object into the
xPos, yPos, and result Bag, clearing them first.
