Computer graphics

A 3D projection of a 4D Pentachoron performing a simple rotation.

Computer graphics includes almost everything on computers that is not text or sound but is normally considered as different from photography. Today almost every computer can do some graphics, and people have come to expect that they will interface with their computer through icons and pictures rather than solely by typing. The term computer graphics has additional meanings:

Today much of our life is affected by computers, and by computer graphics. Whether you see them on television, in newspapers, in weather reports or while at the doctor's surgery, computer images are all around you. A well-chosen graph is able to transform a complex table of numbers into meaningful results. Such graphs are used to illustrate papers, reports, and theses, as well as providing the basis for presentation material in the form of slides and overhead transparencies. A range of tools and facilities are available to enable users to visualise their data, and computer graphics are used in many disciplines.

A textured and lit rendering of a 3d model

In 3D computer graphics, 3D modeling is the process of developing a mathematical, wireframe representation of any three-dimensional object (either inanimate or living) via specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D Printing devices.

Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. Find out more...
