python - openGL(pyglet) 3d 场景无法在 AMD 显卡上正确渲染

Question

我找到了用 pyglet 渲染立方体的代码，我观看了代码附带的视频，它在 Nvidia 显卡上正确显示了立方体渲染。当我在我的 AMD 显卡上尝试代码时它坏了，我该如何解决这个问题？

我已与不和谐的创建者进行了交谈，他已确认他使用的是 Nvidia 卡，非常感谢解决此问题的任何帮助!

您必须确保 pyglet 窗口的默认帧缓冲区具有深度缓冲区。见 Creating an OpenGL context :

config = pyglet.gl.Config(depth_size = 24)
window = pyglet.window.Window(config = config)

如果您的硬件不支持 24 位深度缓冲区，您可能需要尝试 16 位:

config = pyglet.gl.Config(depth_size = 16)
window = pyglet.window.Window(config = config)
