Animation & Graphics

Definition of Animation:

Animation is the process of making the illusion of motion and the illusion of change by means of the rapid succession of sequential images that minimally differ from each other.

Or,

A simulation of movement created by displaying a series of pictures, or frames. Cartoons on television is one example of animation.

Definition of Graphics:

Graphics refers to any computer device or program that makes a computer capable of displaying and manipulating pictures.

Or,

Computer graphics is an art of drawing pictures, lines, charts, etc using computers with the help of programming. Computer graphics is made up of number of pixels.

Types of Graphics Applications

The following are also considered graphics applications:

1. Paint programs: Allow you to create rough freehand drawings. The images are stored as bit maps and can easily be edited.

2. Illustration/design programs: Supports more advanced features than paint programs, particularly for drawing curved lines. The images are usually stored in vector- based formats. Illustration/design programs are often called draw programs.

3. Presentation graphics software: Lets you create bar charts, pie charts, graphics, and other types of images for slide shows and reports. The charts can be based on data imported from spreadsheet applications

4. Animation software: Enables you to chain and sequence a series of images to simulate movement. Each image is like a frame in a movie.

5. CAD software: Enables architects and engineers to draft designs.

6. Desktop publishing: Provides a full set of word-processing features as well as fine control over placement of text and graphics, so that you can create newsletters, advertisements, books, and other types of documents.
