Like Marty said most of it depends on what you would like to do. If you "only" have an easy surface and you know all your projection angles, distances etc a lot of stuff can be done with a DL Also more complex stuff is possible with a detailed planning and content creation (like pre-stretched/curved or UV-unwrapped etc) 3D and mapping on buildings etc is nothing which could be done on the fly and each project needs its own planning.
