Computer graphics
Graphics
means visual manipulation of image. Computer graphics are graphics
created using computers
and, more generally, the representation and manipulation of image data by a computer
with help from specialized software
and hardware.
Typically, the term computer
graphics refers to several different things:
- The representation and manipulation of image
data by a computer
- The various technologies
used to create and manipulate images
- The sub-field of computer science which studies
methods for digitally synthesizing and manipulating visual content.
- Developments in computer graphics have had a
profound impact on many types of media and have revolutionized animation,
movies
and the video game industry.
- Computer generated imagery can be categorized
into several different types: 2D, 3D, and animated graphics.
- As technology has improved, 3D computer
graphics have become more common, but 2D computer graphics are still
widely used.
Computer graphics may be used
in the following areas:
Computer graphics software
- GIMP
- Corel Draw
- Photoshop
GIMP (GNU Image Manipulation Program)
GIMP (GNU Image Manipulation
Program) is an image retouching and editing tool and free and open-source software. There are
versions tailored for most operating systems including Microsoft Windows,
Mac OS X
and Linux.
GIMP
has tools used for image retouching and editing, free-form drawing, resizing,
cropping, converting between different image formats, and more specialized
tasks. Animated images such as GIF and MPEG files can be created using an
animation plugin.
The
developers and maintainers of GIMP strive to be a high-end free software
graphics application for the editing and creation of original images, photos,
icons, graphical elements of web pages and art for user interface elements.
Teachers can make use of the Gimp in three main areas:
(Educational Use of GIMP)
1) A free and relatively easy to use tool to edit images
that you may use when building presentations, handouts, worksheets, tests, web
content, or any other digital or print media. Since it runs on all platforms
and is free, you can use it at home as well as at school.
2) A free tool that will work on any platform
(windows, Mac OS, Linux) including older
machines that you can use to teach students concepts of digital photography,
image editing, or as a tool for students to edit images used in their own
reports and presentations.
3) A tool for scientific analysis of digital images taken
for scientific purposes. It is possible to strip out certain color bands,
adjust brightness and contrast, take measurements, and form conclusions based
upon image data.
AUDACITY (audio editor)
·
Audacity is a free digital audio
editor and recording application, available for Windows, Mac OS X, Linux and other operating systems. The free and

Storyboards
Storyboards are graphic organizers in
the form of illustrations or images displayed in sequence for the purpose of
pre-visualizing a motion picture, animation, motion graphic or interactive
media sequence.
What is a storyboard?
The term “storyboard” is taken from
movie production where it indicates a visual representation of the various
scenes of a film. In e-learning, the
storyboard describes screen by screen what will happen in the final e-lesson.
The storyboard is not a final product. It is an intermediate product which is
then used by Web developers to create the final interactive e-lesson.
Tupi 2D Magic
·
Tupi is a design and authoring tool for digital artists interested in 2D
Animation, offering an interface experience focused on 8-100 years old kids.
Tupi - Features
·

e-content
·
e-content (Electronic-content) is Digital content that can be transmitted
over a computer network such as the Internet.
·
The e-content could be in the following type:
o Short course / unit / module
o Full courseware
e-content - Authoring
·
E-content authoring means
Development of digital content using special authoring tools.
·
Authoring tool is a software package which
developers use to create digital content.
o Eg: Graphic design software,
Video editing software, Animation software, Programming Language etc.
·
Various tools can be
used to produce e-learning content, depending on the file formats we are going
to use and the final product we aim to deliver.
·
In a simplest level,
slide-based tools, like Microsoft PowerPoint or even word processors, are
regarded as e-learning tools. While those tools are not appropriate to present
interactivity, testing and scoring, they can be sufficient to create simple
learning resources.
·
To develop interactive
content, various elements are assembled (e.g. text, illustrations, animations,
audio, video, interactivity). For this we use special tools – known as
authoring tools or authorware – which have been created specifically to develop
e-learning courses.
·
Generally, authoring
tools can be used by people without programming skills. The main advantage of
authoring tools is that they are easier and faster to use, and they require
short development time.
Capabilities/Features of authoring tools for e-content
development
>> interactivity and
navigation – menu-driven content and ability to move throughout the content;
>> editing – content
publisher for easier changes/updates;
