Rather than focusing on realism, the 3D team used an aesthetic approach. Robert Newman, the film’s stereoscopic supervisor said that "We’re using depth more artistically than ever before, and we’re not as concerned with the literal transcription of depth between camera and projector as we are the interpretation of it." To do this, they used a new technique called multi-rigging, which is made up of multiple pairs of virtual cameras. Each pair is used individually on each separate element that adds depth to a scene, like background, foreground, and characters, without adjusting for the relation with the other pairs. When sandwiched together later in production, the result was something that would be visually impossible in the real world, but which created an appealing look to the film.
