本节代码

# 导入需要的库
import glfw
import moderngl as mgl

# 初始化 GLFW
if not glfw.init():
    raise Exception('GLFW出错')

# 创建窗口
window = glfw.create_window(800, 600, 'LearnOpenGL', None, None)
if not window:
    glfw.terminate()
    raise Exception('窗口出错')

# 获得上下文
glfw.make_context_current(window)
ctx = mgl.create_context()

# 视口
def framebuffer_size_callback(window, width, height):
    ctx.viewport = (0, 0, width, height)

glfw.set_framebuffer_size_callback(window, framebuffer_size_callback)

# 渲染循环
while not glfw.window_should_close(window):
    glfw.poll_events()
    glfw.swap_buffers(window)

# 终止 GLFW
glfw.terminate()
