self.window = pyglet.window.Window(640, 480)
This will setup a 2D orthographic projection by default, obviously a
sphere is 3D, which is why you can't see it. You need to setup a 3D
projection. Which you can do with something like this:
glViewport(0, 0, self.window.width, self.window.height)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluPerspective(70, 1.0*self.window.width/self.window.height, 0.1, 1000.0)
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()
This sets up a perspective projection, you can also setup a 3D ortho
projection if you don't want foreshortening. Use glOrtho for that.
If you make your window resizeable put the above code in an
on_resize(width, height) handler method on the window.
