Abstract: The present invention is a projection system. The projection system comprises a plurality of screen segments, each defining a surface in the shape of a toroidal segment having geometric proportions approximating the shape of a predetermined ellipsoidal segment having a first focal point and a second focal point. The screen segments are arranged such that an edge of the surface of one of the screen segments is essentially adjacent along its entire length to an edge of the surface of another screen segment. The projection system also comprises a plurality of projectors equal to the number of screen segments wherein each of said projectors projects an image upon one of the screen segments from the second focal point of the ellipsoidal segment approximated by the screen segment. Preferably, the screen segments are arranged such that the first focal point of each ellipsoidal segment approximated by the surface of the screen segments essentially coincide with each other.
