Definition Animation is a sequence of frames that,

when played in order at sufficient speed, presents a smoothly moving image like a film or video.

2D Animation

2D animation is the creation of moving pictures in a two-dimensional environment. This is done by sequencing consecutive images, or "frames", that simulate motion by each image showing the next in a gradual progression of steps.

Two types of 2D animation :◦ Cel animation : based on changes that occur from

one frame to the next◦ Path animation : moves an object along a

predetermined path on the screen

3D Animation 3D animation is animating objects that appear in

a three-dimensional space. They can be rotated and moved like real objects.

The process of creating 3D computer graphics can be sequentially divided into three basic phases : ◦ Modeling : the process of forming the shape of an object

by creating the broad contours and structure of 3-D objects and scenes

◦ Animation : defining the object’s motion◦ Rendering : the process of generating an image from a

model by giving objects attributes such as color, surface textures, and amounts of transparency, by means of computer programs.

Animation Special Effects

Morphing◦ blending together two images into a series of

images

Warping◦ distorts a single image

Virtual Reality◦ creates an environment that surrounds the user

so that he or she becomes part of the experience

Animation Animated text

◦ using the HTML <blink> command causes text to flash on and off

Animated gif◦ using a software program to

create a series of gif files such as GIF Builder

Director movie◦ animation played using

Shockwave plug-in

3D environments◦ a computer language used to

create 3D images

Advantages and Disadvantages of using Animation

Animation captures the imagination like no other tool, portraying actions and spatial relationships that are not readily visible in reality or that may not exist at all.

Advantages◦ Attracts and holds attention◦ Show otherwise invisible actions or physical processes◦ Increases retention◦ Allows visualization of imagined concepts, objects and

relationships

Disadvantages◦ Requires extensive memory and storage space◦ Requires special equipment for a quality presentation◦ 2D animation cannot depict actuality like video or

photography
