mayavi points3d 渲染不正确

Question

我有这样的代码：

import mayavi.mlab as mlab
import numpy as np
import random 

#white blackground
mlab.figure(fgcolor=(0., 0., 0.), bgcolor=(1, 1, 1))

x1 = y1 = z1 = size1 = []
# number of points
number = 21
for i in range(1,number):
        x1.append(random.randint(-10,11))
        y1.append(random.randint(-10,11))
        z1.append(random.randint(-10,11))
        size1.append(i)

#create spheres
mlab.points3d(x1, y1, z1, size1, resolution=30)
#render
mlab.show()

结果呈现的点数多于 20：

我做错了什么？为什么球体不在随机位置和球体数量？当 number == 2 时，渲染为 3 个球体：

Answer 1

好的，我知道了！第一个错误是：

x1 = y1 = z1 = size1 = []

应该是：

x1 = []
y1 = []
z1 = []
size1 = []

并且最好在mlab.points3d

中加上scale_factor=1
