Since the 1960s, the best way to simulate an object's motion in space has been 3D modeling. An integral element of the CGI process, it's a cumbersome, expensive endeavor, one that requires hundreds of hours of manpower, state-of-the-art technology, and ever-changing algorithms to produce even the shortest sequences. Interactive Dynamic Video, a new technology developed by MIT's Computer Science and Artificial Intelligence Lab (CSAIL), could significantly ameliorate the process. By calibrating the physical behavior of objects--analyzing vibrations in different frequencies in space--IDV can predict how objects will move in new situations, an unprecedented achievement in motion graphics. It could reduce the cost of the CGI process by eliminating the need for green screens.
