Computer graphics deals with creating digital images using computers. It involves hardware, software, and applications. The basic system includes input devices, output devices, and a frame buffer where the image is formed. Computer graphics has evolved from early uses of pen plotters and simple displays in the 1950s-1960s to include wireframe graphics, raster graphics, and increased realism through texture mapping and photorealistic rendering from the 1970s onward. Current applications include video games, virtual reality, scientific visualization, 3D printing, and more.
