Wrt projection we can create a finite point in space and just call it a point at infinity. However it is not infinity?... ;^)
That depends upon the space selected. :)

It's kind of like choosing a "really" large number wrt the naturals. Say, okay, for our purposes, this is infinity, even though its not?
Okay, but why not just use the Extended Complex Plane. It is not infinitely pointless. :)
