给我几个立体几何的manim代码

以下是一些基本的立体几何的manim代码：

1. 三维坐标系

from manim import *

class ThreeDCoordinates(ThreeDScene):
    def construct(self):
        axes = ThreeDAxes()
        self.set_camera_orientation(phi=75 * DEGREES, theta=-45 * DEGREES, distance=5)
        self.play(Create(axes))
        self.wait(1)

2. 立方体

from manim import *

class Cube(ThreeDScene):
    def construct(self):
        cube = Cube()
        self.play(Create(cube))
        self.wait(1)

3. 圆柱体

from manim import *

class Cylinder(ThreeDScene):
    def construct(self):
        cylinder = Cylinder(radius=1, height=2)
        self.play(Create(cylinder))
        self.wait(1)

4. 圆锥体

from manim import *

class Cone(ThreeDScene):
    def construct(self):
        cone = Cone(radius=1, height=2)
        self.play(Create(cone))
        self.wait(1)

5. 球体

from manim import *

class Sphere(ThreeDScene):
    def construct(self):
        sphere = Sphere(radius=1)
        self.play(Create(sphere))
        self.wait(1)

6. 箭头

from manim import *

class Arrow(ThreeDScene):
    def construct(self):
        arrow = Arrow3D(start=[0,0,0], end=[1,1,1])
        self.play(Create(arrow))
        self.wait(1)
