Description

I have those dots that need to convert to a 3D volume using this code But I found that there was something wrong with the compiled period after I entered it.

What I Did

points_3d = [
    (57, 11, 18), (51.22318624, 7.595082359,
                   18.96144895), (63.90307229, 0.612714382, 18.92441008),
    (54.04337196, 13.09810222, -36.37036356), (74.99878683, -66.99592395, 22.63615156)
]

alphashape.alphashape(points_3d, lambda ind, r: 1.0 + any(
    np.array(points_3d)[ind][:, 0] == 0.0)).show()

the crash is this

line 22, in <module>
    np.array(points_3d)[ind][:, 0] == 0.0)).show()

    points_c = rinv.dot(points.T).T
ValueError: shapes (3,3) and (0,) not aligned: 3 (dim 1) != 0 (dim 0)

What I Expected

I want to connect those dots to a 3D volume like those images.
