The efficiency of this approach is demonstrated by an application supporting interactive manipulation of colored highly tessellated models on a large (1.6x0.9 meters) 50Mpixel display that allows for a room-size working space.Categories and Subject Descriptors (according to ACM CCS): B.4.2 [Input/Output and Data Communications]: Input/Output Devices Image Display
