1. ABSTRACT
It is difficult to display an image of any size on the computer screen. This method is
simplified by using Computer graphics. Graphics on the computer are produced by using
various algorithms and techniques. This tutorial describes how a rich visual experience is
provided to the user by explaining how all these processed by the computer. Computer
Graphics involves technology to access. The Process transforms and presents information in a
visual form. The role of computer graphics insensible. In today life, computer graphics has
now become a common element in user interfaces, T.V. commercial motion pictures.
In computer graphics, two or three-dimensional pictures can be created that are used for
research. Many hardware devices algorithm has been developing for improving the speed of
picture generation with the passes of time. It includes the creation storage of models and
image of objects. These models for various fields like engineering, mathematical and so on.
A Cartographer can change the size of charts and topographical maps. So if graphics images
are coded as numbers, the numbers can be stored in memory. These numbers are modified by
mathematical operations called as Transformation. The purpose of using computers for
drawing is to provide facility to user to view the object from different angles, enlarging or
reducing the scale or shape of object called as Transformation.
Animation refers to the movement on the screen of the display device created by displaying a
sequence of still images. Animation is the technique of designing, drawing, making layouts
and preparation of photographic series which are integrated into the multimedia and gaming
products. Animation connects the exploitation and management of still images to generate the
illusion of movement. A person who creates animations is called animator. He/she use
various computer technologies to capture the pictures and then to animate these in the desired
sequence.
