Is it possible?

Hello All,

I have an interesting question:

Is it possible to take what a camera object sees and output it onto a plane as something like a texture? I am thinking of the snipper rifle scope in Halo. It showed an image of what the gun was pointing towards that updated in real time.

If so, that would be awesome!

i think so, base on this?

actually this is more like it

awesome, that looks about like what I was thinking!
