Computer graphics are graphics created using computers and the representation of image data by a computer specifically with help from graphic programs and hardware designed for it. This communication and comprehension of machines and the interpretation of data has been made easier because of computer graphics. The improvements here have meant huge leaps and bounds for graphical industries like gaming and film CGI, as well as media across the board.

The term “computer graphics” was created in the 1960s by William Fetter. The field of computer graphics developed with the emergence of computer graphics hardware. Early projects introduced the CRT as a viable display and interaction interface and introduce the light pen as an input device. Further advances in computing led to greater advancements in interactive computer graphics.
Two dimensional computer graphics are the computer-based generation of digital images, mostly from models. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies.
Vector graphics formats are complementary to raster graphics. Raster graphics are the representation of images as an array of pixels and is typically used for the representation of photographic images. Vector graphics consists of encoding information about shapes and colors that comprise the image which can allow for more flexibility in rendering.
3 Dimensional computer graphics rely on similar algorithms as 2D computer graphics do in the frame and raster graphics in the final rendering display, only with an extra dimension. These new 3D models are now contained within the data file of the graphics, so 3D models are the same as 3D computer graphics.
