Line of Sight culling?

[roadkillguy]

Hi everyone,

I've been writing a game with presumably random boxes. I've implemented view frustrum culling, backface culling, and even display lists. It's still not fast enough for my tastes, and I was wondering if there was any way to tell whether a face will be behind another.

Maybe I could check whether the entire screen has been rendered to?

A point in the right direction would be great. (I'm using c++)

Thanks.

I read somewhere that glBegin() and glEnd() were really slow.. what's the alternative?
