![]() The first cathode ray tube, the Braun tube, was invented in 1897 – it in turn would permit the oscilloscope and the military control panel – the more direct precursors of the field, as they provided the first two-dimensional electronic displays that responded to programmatic or user input. Screens could display art since the Lumiere brothers' use of mattes to create special effects for the earliest films dating from 1895, but such displays were limited and not interactive. The precursor sciences to the development of modern computer graphics were the advances in electrical engineering, electronics, and television that took place during the first half of the twentieth century. Over the past decade, other specialized fields have been developed like information visualization, and scientific visualization more concerned with "the visualization of three dimensional phenomena (architectural, meteorological, medical, biological, etc.), where the emphasis is on realistic renderings of volumes, surfaces, illumination sources, and so forth, perhaps with a dynamic (time) component". Computer graphics has emerged as a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. As technology has improved, 3D computer graphics have become more common, but 2D computer graphics are still widely used. Computer-generated imagery can be categorized into several different types: two dimensional (2D), three dimensional (3D), and animated graphics. Many tools have been developed to visualize data. In the media "such graphs are used to illustrate papers, reports, theses", and other presentation material. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret. Such imagery is found in and on television, newspapers, weather reports, and in a variety of medical investigations and surgical procedures.
