CS602: Computer Graphics
Computer Graphics
Graphics are defined as any drawing or drawing or a special network representing specific purposeful information. Computer Graphics includes the technology of receiving, processing, converting, and presenting visual information related to computer-generated photography (or animation). The field of computer graphics is a vast and varied field that exists between computer science and design. It is interested in the whole process of creating computer-generated images, from the creation of three-dimensional digital models to the process of texting, rendering, and illuminating those models, to the digital presentation of the on-screen presentation.
Why Study Computer Graphics?
There are a number of important reasons for learning computer graphics. We will discuss them under some headings:
Visualization
Many times you happen to do certain tasks that you cannot imagine; for example, as a data architect, you use trees, graphs, and other Abstract Data Types (ADTs) but you cannot visualize them while you have to have an internal search to see what these actually look like. I love showing people what I do. Similarly, at times you would be doing certain tasks that you know but it can be difficult for others to understand so there is a very important need to show things in order to make them understandable.
Requirement
However, there are some areas that require the use of computer graphics. Another example is drawing machines. It is necessary to prepare the machine drawing before actual production. Another difficult requirement is for architects as they have to prepare a complete blue text of the building that they have to build long before the actual construction work begins. AutoCAD and other applications of this type are widely used today in architecture.
Entertainment
A few decades ago, the idea of a 24-hour Cartoons Network was something that was truly taken for granted. That was a time when one had to wait a week before receiving just 15 minutes of entertainment. Thanks to the computer graphics that helped us to have fun with animated movies, cartoons, etc.
The drawings are interesting
We are visible creatures and to us, the image costs a thousand words. If we can remove the text-based static screen and get graphics; it is always interesting to see things in color and movement on the screen. Therefore, graphics are interesting because they incorporate imitation, algorithms, and formats.
Graphics Applications
Due to the rapid growth in the computer industry, computers are now being used as a cost-effective and efficient tool for image production. . Computer graphics applications are found in almost all fields. Here we will discuss some of the key 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 ix. Simulations x. Games
Types of Computer Graphics
Raster Graphics:
In raster, pixels of images are used to draw a picture. Also known as a bitmap image where the sequence of images becomes smaller pixels. Basically, a bitmap shows a large number of pixels together. Pixels appear as small squares on graph paper when the image is zoomed in or enlarged. These images are created by digital cameras, by scanning images into a computer or by raster-based software. Each image can only contain a fixed number of pixels; the number of pixels determines the image quality. This is known as the solution.
Vector Graphics:
Vector Graphics is a digital art that is rendered by a computer using a mathematical formula. Raster images are made of small pixels, making them dependent on editing and are better used to create images. This means that if you measure the vector image, it will retain a smooth, non-pixel appearance, while the raster image will be pixels. In vector images, mathematical formulas are used to draw different types of shapes, lines, objects, and so on.
