What is Computer Graphics?• The term computer graphics

includes almost everything on computers that is not text or sound.

• The development of computer graphics, has made computers easier to interact with, and better for understanding and interpreting many types of data. Developments in computer graphics have had a profound impact on many types of media and have revolutionized animation, movies and the video game industry.

The History of Computer Graphics?• 1950: Ben Laposky created the first

graphic images, an Oscilloscope, generated by an electronic (analog) machine.  The image was produced by manipulating electronic beams and recording them onto high-speed film.

• 1951: UNIVAC-I: the first general purpose commercial computer, crude hardcopy devices, and line printer pictures.

• 1951: MIT – Whirlwind computer, the first to display real time video, and capable of displaying real time text and graphic on a large oscilloscope screen.

• 1960: William Fetter coins the computer graphics to describe new design methods.

• 1961: Steve Russel --  Spacewars, first video/computer game

• 1963: – Douglas Englebart – first mouse– Ivan Sutherland  – Sketchpad,

interactive CG system, a man-machine graphical communication system, it features:

• pop-up menus• constraint-based drawing• hierarchical modeling• utilized lightpen for interaction

What is 2D Computer Graphics?• 2D computer graphics are

graphical images created with the aid of digital computers, in which two-dimensional visual techniques are employed.

• The term may also refer to the field of study or practice of two-dimensional computer graphics methods as a whole.

• In 2D computer graphics, the computer screen may be considered as a canvas on which an image is drawn or composed.

• 2D computer graphics typically do not involve the need for any kind of three-dimensional internal representation of objects or lighting characteristics in the computer; that field is customarily reserved for 3D computer graphics.

• Several techniques exist for rendering 2D graphics on a computer screen; these may be broadly categorized into raster graphics, in which a rectangular array of pixels is drawn to the screen, and vector graphics, in which images are composed of mathematical representations of lines, curves, and other geometric shapes.

What is Computer Animation?• Computer animation can be

described as an art form that involves bringing still images to life using computer technology.

• Animation in this form can apply to images on a computer or to those in film.

• When computer animation is used for movies, it is often called computer-generated imagery.

• To create computer animation, a still, or non-moving image, is first displayed.

• To understand how movement is created with computer animation, consider a blank screen
