A computer ___MASK90___ is a ___MASK90___ who has acquired the knowledge of ___MASK94___ , the study of the theoretical foundations of information and computation and their application . ___MASK31___ are pictures and films created using computers . Usually , the term refers to computer - generated image data created with help from specialized graphical hardware and software . It is a vast and recent area in ___MASK94___ . The phrase was coined in 1960 , by computer graphics researchers Verne Hudson and William Fetter of Boeing . It is often abbreviated as CG , though sometimes erroneously referred to as CGI . A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically . The ability of computers to follow a sequence of operations , called a " program ", make computers very flexible and useful . Such computers are used as control systems for a very wide variety of industrial and consumer devices . This includes simple special purpose devices like microwave ovens and remote controls , factory devices such as industrial robots and computer assisted ___MASK70___ , but also in general purpose devices like personal computers and mobile devices such as smartphones . The Internet is run on computers and it connects millions of other computers . Computer ___MASK49___ , or simply ___MASK49___ , is that part of a computer system that consists of encoded information or computer instructions , in contrast to the physical hardware from which the system is built . A ___MASK83___ , also called a movie , motion picture , theatrical ___MASK83___ or photoplay , is a series of still images which , when shown on a screen , creates the illusion of moving images due to the phi phenomenon . This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession . The process of filmmaking is both an ___MASK53___ and an industry . A ___MASK83___ is created by photographing actual scenes with a motion picture camera ; by photographing drawings or miniature models using traditional ___MASK78___ techniques ; by means of CGI and ___MASK60___ ; or by a combination of some or all of these techniques and other visual effects . Gouraud shading , named after Henri Gouraud , is an interpolation method used in ___MASK31___ to produce continuous shading of surfaces represented by polygon meshes . In practice , Gouraud shading is most often used to achieve continuous lighting on triangle surfaces by ___MASK88___ the lighting at the corners of each triangle and linearly interpolating the resulting colours for each pixel covered by the triangle . Gouraud first published the technique in 1971 . IMAGE ( from Imager for Magnetopause - to - Aurora Global ___MASK68___ ), or ___MASK22___ 78 , was a NASA MIDEX mission that studied the global response of the Earth ' s magnetosphere to changes in the solar wind . It was launched March 25 , 2000 by a Delta II rocket from Vandenberg AFB and ceased operations in December 2005 . Debt , ___MASK72___ , Trade , Africa ( DATA ) was a multinational non - government organization founded in January 2002 in London by U2 ' s Bono along with Bobby Shriver and activists from the Jubilee 2000 Drop the Debt campaign . Henri Gouraud ( born 1944 ) is a French computer ___MASK90___ . He is the inventor of Gouraud shading used in ___MASK31___ . He is the great nephew of general Henri Gouraud . During 1964 -- 1967 , he studied at École Centrale Paris . He received his Ph . D . from the University of Utah College of Engineering in 1971 , working with Dave Evans and Ivan Sutherland , for a dissertation entitled Computer Display of Curved Surfaces . In 1971 Gouraud made the first CG geometry capture and representation of a human face in Wire - frame model and applied his shader to produce the famous human face images showing the effect of his shading were done using his wife Sylvie Gouraud as the model . ___MASK94___ is the study of the theory , experimentation , and engineering that form the basis for the design and use of computers . It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility , structure , expression , and mechanization of the methodical procedures ( or algorithms ) that underlie the acquisition , representation , processing , storage , communication of , and access to information . An alternate , more succinct definition of ___MASK94___ is the study of automating algorithmic processes that scale . A computer scientist specializes in the theory of computation and the design of computational systems . In the mathematical field of ___MASK14___ , interpolation is a method of constructing new data points within the range of a discrete set of known data points .
