Digitally recording dynamic events, such as a sports event, a ballet performance, and a lecture, for experiencing in a spatiotemporally distant and arbitrary setting requires 4D capture: three dimensions for their geometry and appearance over the fourth dimension of time. Cameras are suitable for this task as they are nonintrusive, universal, and inexpensive. Computer Vision techniques have advanced sufficiently to make the 4D capture possible. The authors present the process of 4D digitization of dynamic events with the Virtualized Reality system developed at CMU as the running example, together with a discussion on the general problem of digitizing dynamic events.
