The abstract computer graphics are an important achievement which in the near for 20 year science and technology domain obtains， is produces along with the computer and the auxiliary equipment and It is the modern times computer science and the radar， the great accomplishment which the television and the imagery processing technology development convergence In the shipbuilding， the aerospace， the automobile， electronic， the machinery， the civil engineering， the film and television advertisement， the geography information， spins domain lightly and so on in chemical industry widespread applications， impelled this discipline unceasing development， but unceasingly solves each kind of new topic which in the application proposed， also further enriched and has enriched this discipline The computer appears soon， in order to outputs the graph in the plotting machine and on the cathoderay tube screen， the computer graphics were born along with Now it take develops as carries on the production， the deposit and withdrawal and the management new discipline to the object model and the How the computer graphics (Computer is Graphics) studies uses the digital computer to produce， processing and a demonstration graph The graph concrete application scope is very broad， but looks at only then two kinds from the basic processing technology， one kind is a line， like engineering plat， map， curve graph and so on; Another kind is the light and shade chart， is similar with the In order to produce the graph， first must have the primary data or the mathematical model， like the project personnel forms in one's mind the schematic diagram， the aerial topographic mapping interpret data， the airplane overall concept model， the enterprise manages month statistical data and so These digitized input turns the graphical output after computer The present computer can produce the extremely complex graph， but graph regardless of how complex， it all when becomes by the basic graph Therefore， the study basic graph production algorithm is grasps the computer graphics the This article mainly introduced produces the straight line with the C# language three commonly used algorithms: Numerical differentiation (DDA)， stipples the long-base method and the Bresenham algorithm， then in the introduction stipples the round algorithm， the polygon production
Abstract computer graphics is nearly 20 areas of science and technology to achieve another important achievements， As is the computer and its peripherals and the emergence and development It is modern computer science with the radar， television and image processing technology convergence and the development of the In shipbuilding， aerospace， automotive， electronics， machinery， civil engineering， television advertising， geographic information， Textile Industry wide field of application， which contributed to the discipline continues to develop， and the application to resolve the various new issues and further enrich this subject Arise soon， in order to plotters and cathode ray tube output graphics on the screen， computer graphics attendant was Now， it has to object to the development of the model and graphics creation， access and management of new Computer Graphics (Computer Graphics) is to study how to use digital computer generated， Graphics processing and display of a Graphics specific wide range of applications， from basic technology can handle only two categories of lines， such as engineering drawings， maps， charts curve; Others are shaded maps， photographs and To generate the graphics， there must first of all raw data and mathematical models， such as the idea of the engineering staff draft Aerial topographical interpretation of data， the overall program model， business statistics on the information and so These figures after the importation of processed into computer graphics Now the computer can generate very complex graphics， but the graphics， no matter how complex， It is by the basic combination of Therefore， the learning of basic graphics master algorithm is the basis of computer This paper introduces the C # language generation line of three algorithms : numerical differential Act (DDA) China Midpoint method and Bresenham algorithm， and then explain the midpoint drawcircle algorithm， polygon generation 你可以在网上找一些在线翻译软件，我是用Google翻译的。
