One of the most important aspects of ILM’s work on Minority Report was the development of new techniques for the creation of computer-generated models from photographic images. The photo-modeling technique had significant advantages over the creation of CG models by hand.
Matchmoving is the foundation of much of the work that ILM does. While an artist might match an element he or she creates quite closely to the rest of the objects in the frame, the viewer can still perceive a problem. If one element moves inconsistently against another even in the slightest way, it results in an unnatural “slipping” that audiences immediately pick up on. The complex 2-D work on Minority Report forced ILM to develop new methods for tracking matchmove data.
