如何使用pyopengl和pygame在python中创建一个球体？

pip install pyopengl pygame

import pygame
from pygame.locals import *

pygame.init()
window = pygame.display.set_mode((640, 480))
pygame.display.set_caption('PyOpenGL Sphere')

from OpenGL.GL import *
from OpenGL.GLU import *

glViewport(0, 0, 640, 480)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluPerspective(45, 640/480, 0.1, 50.0)
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()

def draw_sphere():
    quad = gluNewQuadric()
    gluQuadricNormals(quad, GLU_SMOOTH)
    gluSphere(quad, 1.0, 32, 32)

while True:
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
    glLoadIdentity()
    gluLookAt(0, 0, -5, 0, 0, 0, 0, 1, 0)

    draw_sphere()

    pygame.display.flip()
    pygame.time.wait(10)
