Python 为什么这段代码不能在pyopenGL中显示我的纹理

我试图让我的多通道纹理工作，但现在我可以得到简单的纹理工作，任何人都可以用下面的代码。此示例仅将多边形显示为白色，而不是纹理

def loadTexture(name):

    img = PIL.Image.open(name) # .jpg, .bmp, etc. also work
    img_data = numpy.array(list(img.getdata()), numpy.int8)

    id = glGenTextures(1)
    glPixelStorei(GL_UNPACK_ALIGNMENT,1)
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP)
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP)
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img.size[0], img.size[1], 0, GL_RGB, GL_UNSIGNED_BYTE, img_data)
    return id

设置纹理参数或上载数据时，必须调用glBindTexture（GL_TEXTURE_2D，id）：

id = glGenTextures(1)
glPixelStorei(GL_UNPACK_ALIGNMENT,1)
glBindTexture(GL_TEXTURE_2D, id)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img.size[0], img.size[1], 0, GL_RGB, GL_UNSIGNED_BYTE, img_data)

它以什么方式不起作用？你期望看到什么？你实际上看到了什么？更新了，希望这更有意义，谢谢。它以什么方式不起作用？你期望看到什么？你实际上看到了什么？更新，希望这更有意义，谢谢
