2d objects in 3d
I'm working on a 3d engine, which works almost like Resident Evil.
My questions about this are the follwing:
1. What is the technique programmers use, for example in Resident Evil to have pre-rendered, reality-like objects, which aren't really 3d. These object are only(?) "shaders", which let the users see the character if they are in front of that object, but they are "covered" by the object if they are behind it. I think these are only rectangles in 3d space, which the map is shown in a special way on. But that technique would cost too much time to use. Is there a better way to "blend" 3d objects by 2d objects?
2. Is there a name for that technique?
If I didn't express myself correctly, just think about objects, that can be walked around and if you get behind them, you see your character really behind them (blended?), but if you are closer to the camera, than the object, you have your character covering the background (and the object).
