overlapping_spheres(shape: List[int], r: int, porosity: float, iter_max: int = 10, tol: float = 0.01)¶
Generate a packing of overlapping mono-disperse spheres
shape (list) – The size of the image to generate in [Nx, Ny, Nz] where Ni is the number of voxels in the i-th direction.
r (scalar) – The radius of spheres in the packing.
porosity (scalar) – The porosity of the final image, accurate to the given tolerance.
iter_max (int) – Maximum number of iterations for the iterative algorithm that improves the porosity of the final image to match the given value.
tol (float) – Tolerance for porosity of the final image compared to the given value.
image – A boolean array with
Truevalues denoting the pore space
- Return type
This method can also be used to generate a dispersion of hollows by treating
porosityas solid volume fraction and inverting the returned image.
