Question

我有一个使用着色器的小pyopengl代码。我得到以下“信息”日志消息，但不知道他们的意思和文档很差 - 或者我找不到它。

任何人都可以澄清这些意思吗？

INFO     [   MainThread::OpenGL.extensions]  OpenGL Version: 3.3.0 NVIDIA 295.59
INFO     [   MainThread::OpenGL.extensions]  Chose alternate: glCreateShader from glCreateShader, glCreateShaderObjectARB

导入行是：

from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.GLUT import *
from OpenGL.GL.ARB.shader_objects import *
from OpenGL.GL.ARB.fragment_shader import *
from OpenGL.GL.ARB.vertex_shader import *

如果两者都可用，PyOpenGL可以在着色器功能的核心GLSL版本和它们的NVIDIA ARB等效版本之间进行选择。您的信息日志告诉您，您的程序在选择时会选择核心版本。
