如何用opengl批量绘制pyglet中的图元？

import pyglet
from pyglet.gl import *

window = pyglet.window.Window()
batch = pyglet.graphics.Batch()

vertices = [x1, y1, r1, g1, b1,
            x2, y2, r2, g2, b2,
            ...]

vertex_list = batch.add(len(vertices) // 5, GL_POINTS, None,
                        ('v2f', vertices[:2]),
                        ('c3B', vertices[2:]))

@window.event
def on_draw():
    window.clear()
    batch.draw()

import pyglet

window = pyglet.window.Window()
batch = pyglet.graphics.Batch()

vertices = [x1, y1, r1, g1, b1,
            x2, y2, r2, g2, b2,
            ...]

                        ('c3B', vertices[2:]))

@window.event
def on_draw():
    window.clear()
    batch.draw()

pyglet.app.run()
