Animation

Animation is the process of designing, drawing, making layouts and preparation


of photographic sequences which are integrated in the multimedia and gaming
products. Animation involves 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 still images
and then to animate these in desired sequence.

Multimedia is the term used to represent combination of visual and audio


materials gathered from various resources and then added into one single
combination. A multimedia product can be sets of texts, graphic arts, sounds,
animations and videos. Precisely, term multimedia is used to refer visual and
audio materials into a single common presentation which can be played in a
computer including CD ROM or digital video, internet or web technology,
streaming audio or video and data projection system etc.

Modern entertainment industry i.e. film and television has gained new heights
because of advances in animation, graphics and multimedia. Television
advertisements, cartoons serials, presentation and model designs – all use
animation and multimedia techniques.

Types of Animation
 Traditional animation (cell animation or hand-drawn animation)
 Stop motion animation (Claymation, Cut-outs)
 Motion Graphics (Typography, Animated logo)
 Computer animation
   2D animation
   3D animation

Multimedia refers to the term used to describe the combination of both audio and
visual materials that have been gathered from different resources and then have been
put into one single combination. A multimedia product can be set of texts, animation,
videos and even graphic arts. On the other hand, animation refers to the exploitation
and management of still images to come up with an illusion of movement. Multimedia
has a number of animation types used starting from 2D animation up to computer-
generated images. Consider the following types;

To begin with, 2D animation is the most common type of animation in multimedia. It


is a vector-based animation that usually has two basic advantages. The animation is
cheap to develop and has an ease of access characteristic. It does not consume a lot of
time and resources. However, despite the stated advantages, one has to be equipped
with good understanding of keyframes and some related animation software’s.

Also, are the cel or the celluloid or rather traditional animation. This refers to the
original hand-drawn animation that bears too many pictures on paper and they have to
be photographed frame by frame to come up with the illusion of movement. This type
of animation is best for individuals that like color pencils and the likes.

Additionally, another type of animation in the multimedia industry is the stop motion


animation. This type of animation is similar to celluloid animation however in this
type, clay models of the characters are used rather than hand drawings and other that
one has to carefully manipulate them so that they can be produced. This animation has
its own art which can’t be produced in other mediums.  Despite the beauty behind it, it
is labour-intensive and consumes a lot of time.

Consequently, the motion graphics also find their way as the other types of animation
in the multimedia. In this type, a visual effect mechanism involves the moving
graphic elements such as texts or logos and it mostly uses the application software like
after effects. Is s usually best for people who are mastering in advertising and design
of movie opening titles.

Last but not least, another type of animation is the 3D animation. It is also called
computer-generated imagery. This type of animation is usually done by use of
computers and computing software.  it has quite a defined procedure of developing
them just like 2D animation, however, advanced. Once the animation character has
been created, the setting or environment is now developed.

Morphing

Morphing is a familiar technology to produce special effects in image or videos.


Morphing is common in entertainment industry. Morphing is widely used in
movies, animation games etc. In addition to the usage of entertainment industry,
morphing can be used in computer-based trainings, electronic book illustrations,
presentations, education purposes etc. morphing software is widely available in
internet.

Animation industry looking for advanced technology to produce special effects


on their movies. Increasing customers of animation industry does not satisfy
with the movies with simple animation. Here comes the significance of
morphing.
The Word "Morphing" comes from the word "metamorphosis" which means
change shape, appearance or form. Morphing is done by coupling image
warping with colour interpolation. Morphing is the process in which the source
image is gradually distorted and vanished while producing the target image. So
earlier images in the sequence are similar to source image and last images are
similar to target image. Middle image of the sequence is the average of the
source image and the target image.

Morphing Techniques

Morphing techniques may be classified into two based on the ways to specify
their features. They are mesh based methods and feature based methods. In
mesh-based methods, features of the image specified by a non-uniform mesh.
Feature based methods, features of the image specify as line segment or a set of
points. Feature based methods are popular.

Morphing is an animation function which is used to transform object shape from one
form to another is called Morphing. It is one of the most complicated
transformations. This function is commonly used in movies, cartoons, advertisement,
and computer games.
The process of Morphing involves three steps:

1. In the first step, one initial image and other final image are added to
morphing application as shown in fig: Ist & 4th object consider as key frames.
2. The second step involves the selection of key points on both the images for a
smooth transition between two images as shown in 2 nd object.
3. In the third step, the key point of the first image transforms to a corresponding
key point of the second image as shown in 3rd object of the figure.
