Open3Dのvoxelデータの保存形式

コード

extensions = ['nxs', 'nxz', '3ds', 'ply', 'stl', 'obj', 'off', 'wrl', 'dxf', 'dae', 'ctm', 'e57', 'xyz', 'json', 'u3d', 'idtf', 'x3d']

for ext in extensions:
    result = o3d.io.write_voxel_grid(f"sample.{ext}", voxel_grid)
    print (ext, result)

結果: plyのみ対応

MeshLabで保存できる形式のみ試してみました。objはダメなのか…
