Ошибка прозрачности PyGame, Pywin32 API и PyOpenGL ⇐ Python

[Anonymous]

Я пытаюсь сделать прозрачный экран, скрыв цвет фона с помощью win32api.
Это работает с pygame в 2D. Однако, когда я использую pyopengl для создания 3D-платформы, фон не был прозрачным
Я использую 64-битное окно 7, Python 2.7
Вот код для основного. пы:

Вы можете использовать свою собственную модель, просто нужен файл .obj и .mlt, а затем отредактируйте его в строке 33.
В результате вы видно, что фон не стал прозрачным.
