Medicine and Virtual Surgery
Computer graphics has extensive use in tomography and simulations of operations. Tomography is the technique that allows cross-sectional views of physiological systems in X-rays photography.Moreover, recent advancement is to make model and study physical functions to design artificial limbs and even plan and practice surgery.
Computer-aided surgery is currently a hot topic.
ART AND DESIGN
Computer graphics is widely used in Fine Arts as well as commercial arts for producing better as
well as cost effective pictures. Artists use a variety of programs in their work, provided by
computer graphics. Some of the most frequently used packages include:
- Artist’s paintbrush
- Pixel paint
- Super paint
Scientific Visualization and Analysis
Computer graphics is very helpful in producing graphical representations for scientific
visualization and analysis especially in the field of engineering and medicine. It helps a lot in
drawing charts and creating models
User Interfaces
Almost all the software packages provide a graphical interface. A major component of graphical interface is a window manager that allows a user to display multiple windows like areas on the screen at the same time. Each window can contain a different process that can contain graphical or non-graphical display. In order to make a particular window active, we simply have to click in that window using an interactive pointing device.
Graphical Interface also includes menus and icons for fast selection of programs, processing operations or parameter values. An icon is a graphical symbol that is designed to look like the processing option it represents.
Graphics Applications
Due to rapid growth in the field of computing, now computer is used as an economical and
efficient tool for the production of pictures. Computer graphics applications are found in almost all
areas. Here we will discuss some of the important areas including:
- User Interfaces
- Layout and Design
- Scientific Visualization and Analysis
- Art and Design
- Medicine and Virtual Surgery
- Layout Design & Architectural Simulations
- History and cultural heritage
- Entertainment
- Simulations
- Games
Some History
Some History
The term Computer Graphics was coined in 1960 by william fetter to describe the new design methods that he was developing at Boeing .He created a series of widely reproduced images on a plotter exploring cockpit design using a 3D model of a human body.
Why Study Computer Graphics?
Definition
Computers accept process, transform and present information.
Computer Graphics involves technology to accept, process, transform and present information in
a visual form that also concerns with producing images (or animations) using a computer.
Why Study Computer Graphics?
There are certain important reasons to study computer graphics. We will discuss them under
certain heads:
a. Visualization
I like to see what I am doing. Many a times it happens that you perform certain tasks which you
cannot visualize; for example as a student of data structures, you implement trees, graphs and
other Abstract Data Types (ADTs) but you cannot visualize them whereas you must be having an inner quest to see what these actually look like.
I like to show people what I am doing. Similarly at certain times you would be performing certain
tasks which you know but it would be difficult for others to understand them so there is very
important requirement of showing the things in order to make them understandable.
b. Graphics is interesting
We are visual creatures and for us a picture is worth a thousand words. If we can get rid of text
based static screen and get some graphics; its always interesting to see things in colours and
motion on the screen. Therefore graphics is interesting because it involves simulation, algorithm,
and architecture.
c. Requirement
Well there are certain areas which require use of computer graphics heavily. One example is
drawing of machines. It is required to prepare drawing of a machine before the actual production.The other heavy requirement is for architects as they have to prepare a complete blue print of the building they have to build long before the actual construction work gets underway. Autocad and other applications of the kind are heavily used today for building architecture.
d. Entertainment
Merely a couple of decades back, the idea of a 24 hours Cartoons Network was really a far
fetched one. That was the time when one would wait for a whole week long before getting an
entertainment of mere 15 minutes. Well thanks to computer graphics that have enabled us to
entertain ourselves with animated movies, cartoons etc.
