Oh,my mistake,i''m very sorry!
my meaning:as we all know, we can make a background for a scene.for example,the mountains in a distance in NFS r made of the texture,and it''s mapping as the background,so we can see the mountains stand beyond,like the true mountain model.
i think it can be mapped on some very big polygons,and then put them into the scene to be as the background.
but i think this way is no good.i think there may be a better way to make it.
every body, do u understand it?

It is probably a texture mapped on a quad. Note, the quad doesn''t have to be a square mile in size and a couple miles away: It''s just rendered first, without zbuffer writing.

ok.....i see. does that mean we make a screen,and the texture for background we want is mapping on that?

load in your texture say a 256x256 sized one (though thisll result in a bit of stretching to get rid of the stretching use the top 3/4 )
ok load in your texture + now u want to draw this texture over the whole background right?
