Welcome to the documentation for the dla_3d package!

class dla_3d.initialize_system.initialize_system(k)

Bases: object

Methods

find_center()

Find the center of the grid and fill it.

initialize_grid()

Initialize the grid using the parameters from the constructor.
__init__(k)

Constructor for this class.

Parameters
k : int

exponent

N : int

base

grid : array-like

3d grid of dimensions N x N x N

find_center()

Find the center of the grid and fill it.

initialize_grid()

Initialize the grid using the parameters from the constructor.

class dla_3d.random_walk.random_walk(grid, center, inner_radius, outer_radius)

Bases: object

Methods

initialize_walk()

Initializes the position of the random walkers.

test_vicinity(grid, center, x0, y0, z0)

Search surroundings of a point for filled points and check distance from center.

walk(grid)

Random walk of an initialized walker.
__init__(grid, center, inner_radius, outer_radius)

Constructor for random walk.

Parameters
grid : array-like

Three-dimensional grid with seed in the center, initialized by the initialize_system class.

center : array-like

Position of the seed.

inner_radius : int

Radius of the inner sphere, where random walkers start their path.

outer_radius :

Radius of the outer sphere. If a walker leaves the outer sphere, its walk will be stopped and a new walker will be released.

initialize_walk()

Initializes the position of the random walkers.

Returns
x, y, z : int

Initial position of the random walker on the inner sphere.

test_vicinity(grid, center, x0, y0, z0)

Search surroundings of a point for filled points and check distance from center.

Parameters
grid : array-like

Initialized grid with filled center.

center : array-like

Position of the center.

x0, y0, z0 : int

Position of the point in question.

Returns
dist : int

Distance of the point from the center.

isum : int

Sum of grid values in the vicinity of the point. Neighbour points can only vary in one point, i.e. [x0, y0, z+1] or [x0-1, y0, z0], but not [x0+1, y0+1, z0].

walk(grid)

Random walk of an initialized walker.

Returns
grid : array-like

Updated grid after random walker has finished.
