Computer graphics 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 computer science. 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 computer-generated imagery (CGI).
Some topics in computer graphics include user interface design , sprite graphics , vector graphics , 3D modeling ,
shaders, GPU design, implicit surface visualization with ray tracing, and
computer vision , among others. The overall methodology depends heavily on the underlying sciences of
geometry , optics, and physics .
Computer graphics is responsible for displaying art and image data effectively and meaningfully to the user. It is also used for processing image data received from the physical world. Computer graphic development has had a significant impact on many types of media and has revolutionized
animation, movies, advertising , video games , and graphic design generally.
