I'm just wondering if there are better and faster ways to place static bitmap backgrounds, and have 3D objects move in front of them. I tried a flat piece of polygon as the background but from what I could do (since I'm new to this) it needs to be refreshed at every frame and that makes it slow.

Is there a better way to implement this with OpenGL? Or is DirectX a better choice? I would prefer it more if it's for OpenGL since I've been toying with it a little and have at least some beginner-level knowledge on it though. Thanks for any help in advance.
