   Cubemap Problem
  Hello everyone! I'm trying to use environment mapping in my OpenGL program to implement a reflection effect. First I created a cubemap with 6 bitmap, and then I drew a solid sphere. I thought I would have been able to watch all the 6 reflection surface when I was moving the camera in the space. That is to say, when I look at the sphere from east to west, or from south to north, the reflected texture on the sphere should be different. However, no matter how I move my camera, I see only one same image toward me, just like the sphere is rotate to fix your camera when you move. I don't know wether I have expressed my question clearly, and is there someone else who has met the same problem? Help me please. Thank you very much!   
  for example, the six surfaces on the cube is maybe the flags of Germany\UK\Italy\France\Spain\Portugal, no matter which position I stand to watch the ball, I see the UK flag is just towards me...
