Figure 6.19. (a,b) Matchmoving is the basic tool for inserting realistic visual effects into back-
ground plates. In this example from Transformers: Dark of the Moon , spaceships fly around the
building and land on its right side. (c,d) Matchmoving is also commonly used for set extension.
In this example from A Beautiful Mind , only a small piece of the set was built on a soundstage,
and the rest of the building was digitally generated. Transformers: Dark of the Moon ©2011

Many companies do pure photogrammetry for set reconstruction— they just take
a lot of pictures, and use structure from motion tools to determine 3D points in the
scene. You can get a lot done that way, but spatial accuracy is often a problem.
