torchhull

torchhull is an extremely fast Torch C++/CUDA implementation for computing visual hulls from mask images and comes with Python bindings through charonload:

import torchhull

verts, faces = torchhull.visual_hull(masks,  # [B, H, W, 1]
                                     transforms,  # [B, 4, 4]
                                     level,
                                     cube_corner_bfl,
                                     cube_length,
                                     masks_partial=False,
                                     unique_verts=True,
                                    )
