Python OpenGL VAO -如何对顶点和颜色数据使用单独的数组

import numpy as np
from OpenGL.GL import *
from OpenGL.GLUT import *

vertices = np.array([
    -0.5, -0.5, 0.0,  # 第一个顶点的坐标
    0.5, -0.5, 0.0,   # 第二个顶点的坐标
    0.0, 0.5, 0.0     # 第三个顶点的坐标
], dtype=np.float32)

colors = np.array([
    1.0, 0.0, 0.0,  # 第一个顶点的颜色（红色）
    0.0, 1.0, 0.0,  # 第二个顶点的颜色（绿色）
    0.0, 0.0, 1.0   # 第三个顶点的颜色（蓝色）
], dtype=np.float32)

glBufferData(GL_ARRAY_BUFFER, vertices.nbytes, vertices, GL_STATIC_DRAW)

stride = 3 * vertices.itemsize
