porespy.networks.rescale_network#

porespy.networks.rescale_network(network, voxel_size)#

Rescale a network’s geometric properties to a new voxel size.

Networks extracted by porespy carry their original voxel_size in param.voxel_size. This function uses that value to compute a scale factor and rescales every length/area/volume field accordingly, so the output is identical to what a fresh extraction at the new voxel size would have produced (modulo float precision).

Parameters:

  • network (dict) – A network produced by snow2, regions_to_network, or magnet. Must contain param.voxel_size and param.ndim.

  • voxel_size (scalar) – The new voxel size, in the same units as the original.

Returns:

rescaled – A new network dict with all dimensional fields rescaled and param.voxel_size updated to the new value. The input is not mutated.

Return type:

dict

Notes

Anisotropic voxel sizes (i.e., a tuple stored in param.voxel_size) are not supported; if all axes share the same value, that scalar is used, otherwise an exception is raised.
