Okay, me and my friend where discussing ideas for our game. And I was wondering if this one was even possible?

Okay, like say on the HUD we have some square boxes.

Yea, hope that helps you get the idea. Okay, so say I define a face icon for each player, would it be possible to make it come up in the boxes only when they are in your view? Now remember, before anyone flames me, I am not asking for someone to hand me the code I am just wondering if this would even be possible to do before I try to do it.
