3d mapping inspiration

Here is a small collection of videos from youtube showing different 3d mapping projects from around the globe. I have to find out the difference between true 3d mapping and what appears to be just using the sides of buildings as a huge screen and integrating the surface into the animation. For instance, for the 2d projections, it would be easy to use after effects or apple motion to produce the content. But what software is used for the true 3d mapping eg the superbien video or the Toyoto promotion.
