是itertools.product的更快替代品

Question

是否有更快的方法来获得x,y,z的所有坐标组合itertools.product？例如,我有范围:x:10-310,y:10-310和z:0-65.

编辑

例如,我必须将所有坐标放在这里的聚合数据中:

points1 = vtk.vtkPoints()                      
for coords in itertools.product(x1,y1,z1):
   points1.InsertNextPoint(coords)
boxPolyData1 = vtk.vtkPolyData()
boxPolyData1.SetPoints(points1)

Answer 1

用途np.mgrid:

import numpy as np

x, y, z = np.mgrid[10:311, 10:311, 0:66]

我以为你想要终点310和65包容性.
