Creating a 3d Enviorment

Hey guys, just one more question…

I’m trying to create movement in 3d enviorments, like moving through hall ways and such, which I am pretty good at now, but how would I go about ending the transition?

Pretty much it finishes the hallway, then a picture slowly fades in. I was wondering if it could some how collapse on itself, and if so, would the best way be to use lines?:-/
