What is animation l.jpg
What is Animation?

50 years ago Walt Disney created animated objects such as Mickey Mouse.

Today the process used to create animated objects has had to change.

In fact, it continues to change.


Animation l.jpg
Animation

The word “animation” is a form of “animate,” which means to bring to life.

Thus when a multimedia developer wants to bring an image to life, animation is used.

For example, a spinning globe is it better to film the motion on video, or is animation a better solution.


The power of motion l.jpg
The Power of Motion

Visual effects such as wipes, fades, zooms, and dissolves are available in most authoring packages.

But animation is more than wipes, fades, zooms, and dissolves.

Until Quick Time and AVI motion video became more common place animations were the primary source of dynamic action in multimedia.

Animation

adds visual impact to your multimedia projects and Web pages

Many multimedia applications provide animation tools,

.

You just have to look at it & enjoy it!

Especially if your “flying’”

Animation

First you should understand the principles of how the eye interprets the changes is sees as motion.


Principles of animation l.jpg
Principles of Animation

Animation is possible because of a a biological phenomenon known as persistence of vision

And

The psychological phenomenon called phi .

An object seen by the human eye remains chemically mapped on the eye’s retina for a brief time after viewing.

Combined with the human mind’s need to conceptually complete a perceived action.

This makes it possible for a series of images that are changed very slightly and very rapidly, one after the other, seem like continuous motion .

Animation adds visual impact. Persistence of vision allows a series of separate images to blend together into a visual illusion of movement.


Kinematics l.jpg
Kinematics

Kinematics is the study of the movement and motion of structures that have joints, such as a walking man.

Animation and frame rates l.jpg
Animation and Frame Rates

TV video builds 30 entire frames or pictures every second.

Movies are shot at a shutter rate of 24 frames per second, but using projections tricks the flicker is increased to 48.

On some projectors each frame is shown 3 times before the next frame, for a total of 72 flickers per second which helps eliminate the flicker effect.

Cel Animation – plays at 24 frames per second.


Animation techniques l.jpg
Animation Techniques

Computers have taken a great deal of handwork out of the animation and rendering process.

And commercial films such as Jurassic Park, Beauty and the Beast, Toy Story, and Shrek have utilized the power of the computers.


2 d animation l.jpg
2-D Animation

Two types:

Cel animation

Path animation


Cel animation l.jpg
Cel Animation

Made famous by Disney

24 frames per second therefore a minute may require as many as 1,440 separate frames.

Cel animation: is based on changes that occur from one frame to the next.

Cel stands for celluloid which is a clear sheet with images drawn on them.

The celluloid images are place on a background that is usually stationary.

The background remain fixed as the images changes.


Path animation l.jpg
Path Animation

Moves an object along a predetermined path on the screen

The path can be a straight line or have a number of curves.

Starts with keyframes (the first and last frame of an action).

The series of frames in between the keyframes are drawn in a process called tweening.

Tweening requires calculating the number of frames between keyframes and the path the action takes, and then actually takes, and then sketches a series of progressively different outlines.

Computer animation l.jpg
Computer Animation

Typically employees the same logic and procedural concepts as cel animation

You can usually set your own frame rate

At 15 frames a second the animation may appear jerky and slow

2-D animation can be an acceptable alternative to the expense of creating video

418 Kilobytes

5 fps

3-D Animation involves three steps: modeling, animation, and rendering

Modeling – the process of creating objects and scenes

Animation – the process of defining the object’s motion

Rendering – the final step in creating 3-D animation.

Morphing is the process of blending two images into a series of images

Warping allows you to distort a single image

Virtual reality (VR) creates an environment that surrounds the user so that they become part of the experience.
