Now, with the advances in computer hardware and software, graphics has come a full circle and, more and more people are teaching and learning, communicating and sharing their ideas through the medium of graphics.
By graphics, we mean any sketch, drawing, special artwork or other material that pictorially depict an object or a process or otherwise conveys information, as a supplement to or instead of written descriptions, and the utilisation of computers to accomplish such tasks leads to a new discipline of computer graphics.
Traditionally, graphics has referred to engineering drawings of buildings, bridges, machine parts etc. In recent decades, graphics has ventured into industrial design, advertising and other artistic endeavours. During the last few years, even newspapers and periodicals aimed at the common man have begun to utilise graphics to present quantitative news such as selection results and production statistics.
Computer graphics can do all this and more. In fact, the power and easy availability of computer graphics have increased the use of pictures to replace and augment words to describe, educate, or inform a wide variety of audiences, on a wide variety of subjects.
The meaning of the term Graphics is Graphical Tricks. Every image or picture is in fact a graph and when different mathematical tricks are used to manipulate some change in its properties like shape, size, motion etc. Computer Graphics is a complex and diversified field. A Picture is a fundamental cohesive concept in Computer Graphics. Each picture consists of points called pixels Picture-element. If we consider a complex picture, then complex database for pixels are considered, hence, complex algorithm are required to access them.
These complex databases contain data organised in various data structures such as ring structures, B-tree etc. Work is going on in various fields but computer vision is a hot topic, where research tackles the general problem of estimating properties of an object or scene through the processing of images, both 2D photographs and 3D range maps.
Within this broad scope, we investigate efficient ways to model, capture, manipulate, retrieve, and visualise real-world objects and environments. Once you get into computer graphics, you'll hear about all kinds of applications that do all kinds of things. While working on a project, you may need images, brochures, a newsletter, a PowerPoint presentation, poster, DVD etc.
Thus, the question arises what software do I need to get my job done. The section will help to straighten all of that out in your head. Hopefully, if you know what does what, you won't waste money duplicating purchases, and when other designers or co-workers are talking shop, you'll know what is going on.
Graphic design applications are basically broken down on the basis of a few considerations. The first two considerations are, "Is your project for print, or web".
When I say web, what I really mean is monitor based publishing. This means that you are going to see your work on a computer screen, and television, or a big screen projector. So, as you read through this section, whenever we say "web based", we mean monitor based. If you are creating, or learning to create graphic design, computer art, or maybe "Digital Media" is the term that we should use, then it's a good thing to understand the function of each application. There are many applications in the market and most of them are expensive.
Now, in such a situation where no one stands with you, your ultimate companions are the slides which have some information either in the form of text, charts, and graphs etc. If you think more deeply, these are nothing but the ways some 1.
Vector 2. You may wonder which one of these is a better format when exporting to some software PowerPoint or Keynote or impress. The truth is that there are different situations that call for different methods, but here are some things to look out for.
For instance, vectors are objects that are defined by anchor points and paths, while bitmapped graphics are digital images composed of pixels. The advantage of using vector graphics is that they are size independent, meaning that they could be resized with no loss in quality.
Bitmapped graphics, on the other hand, provide a richer depth of colour but are size dependent and appear at the stated 72 dpi size. File formatSay, we want an image of a Fly. The wings are partially transparent and to represent that in our presentation what be problematic if proper file format is not there. This choice of file format is hidden in the software that you may be using. PowerPoint works well with both these files when creating transparent backgrounds but generally PNG creates smaller file sizes with no loss of quality.
Painting and DrawingWhen we talk about graphics, we mean pictures, and pictures can be either illustrations or photographs.
If you want to get graphics into a Web page or multimedia presentation, you either have to create them in some kind of graphics application by drawing or painting them right there in the application, or bringing them into the application via a digital camera or scanner, and then editing and saving them in a form suitable to your medium. Many software applications offer a variety of features for creating and editing pictures on the computer. Even multimedia authoring and word processing programs include some simple features for drawing on the computer.
So, painting and drawing application in computer graphics allows the user to pick and edit any object at any time. The basic difference is as follows:Drawing: in a software application means using tools that create "objects," such as squares, circles, lines or text, which the program treats as discrete units.
If you draw a square in PowerPoint, for example, you can click anywhere on the square and move it around or resize it. It's an object, just like typing the letter "e" in a word processor. Painting: functions, on the other hand, don't create objects. If you look at a computer screen, you'll see that it's made up of millions of tiny dots called pixels.
You'll see the same thing in a simpler form if you look at the colour comics in the Sunday newspaper -lots of dots of different colour ink that form a picture. Unlike a drawing function, a paint function changes the colour of individual pixels based on the tools you choose.
In a photograph of a person's face, for example, the colours change gradually because of light, shadow and complexion. You need a paint function to create this kind of effect; there's no object that you can select or move the way you can with the drawn square i. More painting program allows placement of such predefined shapes as rectangles, polygon and canvas.
Any part of the canvas can be edited at pixel level. Ankur Pachauri MCA Department RATM, MathuraPage 9The reason why the differences are important is that, as noted earlier, many different kinds of programs offer different kinds of graphics features at different levels of sophistication, but they tend to specialise in one or the other. For example:1 Many word processors, like Word, offer a handful of simple drawing functions. They aren't that powerful, but if all you need is a basic illustration made up of simple shapes to clarify a point, they're fine.
Of these, some are all-purpose programs, like KidPix, which offers both drawing and painting functions. KidPix is targeted specifically at children; it has a simplified interface and lacks the sophisticated functions a professional artist might want.
Other programs, like Adobe Photoshop, specialise in painting functions, even though they may include drawing functions as well. Painter is a paint-oriented program that offers highly sophisticated, "natural media" functions that approximate the effects of watercolours or drawing with charcoal on textured paper. Other graphics programs, such as Adobe Illustrator, specialise in drawing for professional artists and designers; AutoCAD is used mainly for technical and engineering drawing.
That is, they allow you to create or import text and graphics and, perhaps, sound, animation and video. Most of the graphics features in these types of programs are limited to drawing functions because they assume that you will do more complex work in a program dedicated to other functions e.
Some multimedia authoring systems, however, also offer painting and drawing functions. By the way, the differences in composition programs are mainly in the form of their output: The Queen of Page Layout is Quark Express, owned by Quark Express and Indesign is the King owned by Adobe and finally there is Microsoft Publisher, which is very easy to use. Vectors are wonderful because they print extremely well, and you can scale them up to make them large, or scale them down to make them small, and there is no distortion.
Adobe Illustrator is the King of Vector Programs, hands down. In Adobe Illustrator, you can create a 12 foot, by 12 foot document. If we are going to make anything that is going to be printed, we are doing it in Illustrator. Anything that you create in Illustrator, and the text you use, will come out great.
The thing is, Illustrator is hard to learn. It is not an intuitive program at all. This is because vectors use control points called paths and anchor points. To someone new, they are hard to understand, find, and control. That's another story. If you are making a poster, you would make your logo, artwork and text in Illustrator. You would still manipulate your images in Photoshop, and then, "place" them to the Illustrator. Scientific VisualisationIt is difficult for the human brain to make sense out of the large volume of numbers produced by a scientific computation.
Numerical and statistical methods are useful for solving this problem. Visualisation techniques are another approach for interpreting large data sets, providing insights that might be missed by statistical methods. The pictures they provide are a vehicle for thinking about the data. As the volume of data accumulated from computations or from recorded measurements increases, it becomes more important that we be able to make sense out of such data quickly.
Scientific visualisation, using computer graphics, is one way to do this. Scientific visualisation involves interdisciplinary research into robust and effective computer science and visualisation tools for solving problems in biology, aeronautics, medical imaging, and other disciplines.
The profound impact of scientific computing upon virtually every area of science and engineering has been well established. The increasing complexity of the underlying mathematical models has also highlighted the critical role to be played by scientific visualisation.
