Besides 3D effects, the filmmakers also used 2D artworks and drawings for specific elements and sequences in the film, including Elsa's magic and snow sculptures, as well as freezing fountains and floors. The effects group created a "capture stage" where the entire world of Frozen gets displayed on monitors, which can be "filmed" on special cameras to operate a three-dimensional scene. "We can take this virtual set that's mimicking all of my actions and put it into any one of our scenes in the film," said technology manager Evan Goldberg.
